l Local announcement services, so as to save the MRS announcement resource and thesending of the customized signal tone

l Local audio mixing services. When the MRS resource is insufficient or does not exist, theaccess gateway can provide the audio mixing services for the on-phone meeting, three-party service, and call waiting.

l Pulse digit collection and dual tone multi-frequency (DTMF) digit collection

l Activating the message waiting indicator service through voltage ascending or frequencyshift keying (FSK)

l Virtual access gateway (VAG) function, that is, one AG is divided into multiple VAGs andeach VAG provides services independently under the control of the MGC

l Hairpin connection, in which the internal calls of a UA5000 are connected through theTDM fabric without consuming the DSP resources

l AG overload control, including CPU overload control and DSP overload control

l Pulse metering and polarity reversal metering

l Automatic dialing test function, that is, the subscribe lines are tested traversely instead ofone by one dialing manually

l Call measurement

3 Function FeaturesUA5000 Universal Access Unit

Product Description


l Measurement of protocol packets and FE port traffic

3.1.2 ReliabilityThis section describes the reliability of the AG.

l Supports device authentication when the UA5000 acts as an AG. The illegal access isforbidden through authentication.

l Supports the active/standby configuration of the IP address of the signaling

l Supports dual homing. When the primary MGC is down, the AG automatically switchesto a secondary MGC.

l Supports the standalone function. If the communication between the MGC and the AGfails, the internal subscribers of the AG can still call each other through internal switching.

l Supports escape channels. When the communication between the MGC and the AG fails,the narrowband subscribers of the AG can still make calls to the PSTN through escapechannels.

l Supports overload control. When the AG or the MGC is overloaded, the AG givespreference to calls of higher priorities.

3.1.3 Voice QualityThis section describes the voice quality of the AG.

The UA5000 ensures the high voice quality through:

l Voice activation detection (VAD)

l Comfortable noise generation (CNG)

l Jitter buffer dynamic adjustment

l Echo cancellation (compliant with ITU-T G.165/G.168)

l Packet loss compensation

l DTMF detection/generation

l (Optional) Tx/Rx gain control

The UA5000 guarantees QoS for the voice services through:

l Priority configuration of voice and data services

l IP type of service (ToS)

l Differentiated service code point (DSCP)

l Virtual local area network (VLAN) priority

l Voice quality enhancement (VQE)

The UA5000 also supports the Real-time Transport Control Protocol (RTCP) packet detection,so as to realize the voice quality monitoring (VQM) function.

3.1.4 Integrated AGThis section describes the features of the integrated AG.

An integrated AG provides VoIP and broadband services at the same time. It aggregates allservice streams on the GE port of the IPMB board for uplink.



In the integrated AG, different service streams can be tagged with different precedence to ensuretheir QoS.

l Send them through different VLANs, so as to logically separate traffic of different types.

l Tag them with different ToS/DSCP precedence, so as to provide an expedited forwardingmechanism based on layer 3 (L3).

l Tag them with different 802.1p precedence, so as to provide an expedited forwardingmechanism based on layer 2 (L2).

l With the Bidirectional Forwarding Detection (BFD) Protocol, the UA5000 can detect linksfor important services, such as the VoIP service, and management packets. Once a linkfailure is detected, the system automatically switches the service to the standby link, so asto protect the service.

l Be interconnected with the Quidway NetEngine80E of Huawei

NOTE

To enable the BFD function, the device on the peer end must support the BFD function.

l A frame is transmitted according to its public VLAN tag. In this way, the private VLANand services are transmitted to the peer end transparently.

Stacking VLAN

Stacking VLAN is a VLAN feature that allows the UA5000 to add two 802.1Q VLAN tags toan untagged frame.

A stacking VLAN has the following features:

l Supports the multi-ISP wholesale service. With the stacking VLAN, the inner VLAN tagidentifies a subscriber, and the outer VLAN tag identifies the Internet service provider (ISP)of the subscriber. For the service, the upper network must work at L2, and forward packetsbased on the VLAN tag and the MAC address.

l Supports the expansion of the number of VLANs by identifying a subscriber with two layersof VLAN tags. To support this feature, the associated broadband remote access server(BRAS) must support the authentication of the two layers of VLAN tags.

MUX VLAN

A MUX VLAN is a VLAN that contains one or multiple uplink ports, but contains only oneservice port. Any two MUX VLANs are isolated.

One-to-one mapping can be set up between a MUX VLAN and an access subscriber. Hence, aMUX VLAN can uniquely identify an access subscriber. The MUX VLAN is used whensubscribers are distinguished according to VLANs.

Escape Channel

By connecting to the foreign exchange subscriber (FXS) interface of the PSTN exchange throughthe FXO interface, the UA5000 provides an escape channel for the narrowband subscribers.When the communication between the UA5000 and the MGC fails, the narrowband subscribersof the UA5000 can still make calls through the escape channel.

l The escape channel supports only the outgoing calls.

l The numbers that can be called are decided by the preset digitmaps.

DDI

By connecting to the FXS interface of the enterprise private branch exchange (PBX) throughthe FXO interface, the UA5000 supports the DDI function for the PBX subscribers. With thisfunction, you can directly call a PBX subscriber by dialing the access code of the enterprise andthe extension number of the PBX subscriber.



The UA5000 provides an FXS interface to connect to the FXO interface of the PBX. In this way,the PBX subscribers can directly call subscribers outside the enterprise.

4.2.3 R2 Packet ApplicationThis section describes the application of the UA5000 in R2 packet.

The UA5000 connects to the PBX through an E1 port and interacts with the PBX through R2signaling.

Network Description

In the QinQ application, the packet transmitted in the backbone network has two 802.1q tags: apublic VLAN tag and a private VLAN tag.

l On the subscriber sideThe enterprise subscriber adopts the access. The traffic then is delivered in the VLAN mode.As shown in Figure 4-8, the subscribers of VLAN 1 and VLAN 2 can access theUA5000, on which QinQ is enabled. The UA5000 adds a public VLAN (VLAN 3) tag tothe subscriber packet, and forwards the packet to the upstream network.

l On the network sideIn the MAN backbone network, the packet is transmitted through the public VLAN tag.After the packet reaches the UA5000 on the other side of the backbone network, theUA5000 removes the public VLAN tag from the packet, and forwards the packet to theuser device.

The QinQ networking saves the public VLAN ID resources to transparent transmission of theprivate VLANs over the public network. The QinQ networking provides a simple L2 VPNchannel to transparently transmit private VLANs and services to the peer end.

4.2.6 VLAN Stacking ApplicationThis section describes the application of the UA5000 in VLAN stacking.

Service Description

The UA5000 supports VLAN stacking to provide the VLAN extension and private linewholesale service.


Product Description


l VLAN extension service: It is used to extend the number of VLANs and to identify thesubscriber.

l Private line wholesale service: If it is needed, the upstream network must be in L2 workingmode, so that the packets can be directly transmitted through VLAN IDs and MACaddresses.

Network Description

As shown in Figure 4-9:

l The subscriber packet at the subscriber side is untagged before reaching the UA5000. Whenthe packet reaches the UA5000, the UA5000 adds two VLAN tags (outer VLAN tag andinner VLAN tag), and then transmits the packet to the upper layer network.

l When the packet at the network side reaches the UA5000, the UA5000 removes the twoVLAN tags from the subscriber packet. Then the UA5000 forwards the packet to thesubscriber device.

The stacking VLAN:

l Supports the expansion of the number of VLANs by identifying a subscriber with two layersof VLAN tags.

l Private line wholesale service: With the stacking VLAN, the inner VLAN identifies asubscriber, and the outer VLAN identifies the serving Internet service provider (ISP) of thesubscriber.



4.2.7 Triple Play ApplicationThis section describes the triple play application of the UA5000.

Service Description

The UA5000 is capable of simultaneously providing voice, data, and video services for terminalsubscribers simultaneously with appropriate QoS. Such a scenario is called triple play.

The UA5000 supports both the multi-PVC triple play solutions.

l Multi-PVC triple play solution

Different PVCs are used to distinguish traffic from different services.

The UA5000 supports mapping different PVCs to different service VLANs, and addingdifferent 802.1p priority tags to the VLANs.

In this application, a gateway must provide multiple Ethernet ports and support bindingbetween the Ethernet port and the PVC.

Product Description


In this scenario, triple play subscribers are connected to the UA5000 through the home gateway.The UA5000 provides voice service, data (Internet access) service, and video service for thesubscribers.

l Voice serviceThe VoIP packets reach the UA5000 through the home gateway. The UA5000 thentransmits the packets to the NGN network, or to the PSTN network through a trunk gateway(TG).

l Data serviceThe data packets from PCs are transmitted to the UA5000 through the home gateway. Afterbeing processed by the BRAS, the data packets are forwarded upstream to the IP network.

l Video service– Video service is delivered over IP multicast traffic, supplying subscribers with various

program sources.– The UA5000 manages the multicast subscribers' authorities and the programs based on

IGMP proxy and controllable multicast. After the subscribers have passed theauthentication, the UA5000 transmits the IGMP protocol packets to the equipment atthe aggregation layer.

– The video server transmits the video service traffic to the UA5000 through the backbonenetwork and the convergence network. The UA5000 forwards the traffic to thesubscriber terminals based on the authentication results.

– At the subscriber end, the set top box (STB) is used to terminate video signals, performmedia conversion, and control program switching.

The triple play solution enables multi-services access simultaneously on the same subscriberterminal.

A.2 Technical Specifications of the U InterfaceThis section describes the technical specifications of the U interface based on 2B1Q encodingmode.


Product Description


A.2.1 OverviewThis section describes the definition of the U interface.

A.2.2 Basic Features of the U InterfaceThis section describes the basic features of the U interface.

A.2.3 Specifications and Program of the U InterfaceThis section describes the specifications and program of the U interface.

A.2.4 Activation and Deactivation of the U InterfaceThis section describes how to activate and deactivate the U interface.

A.2.5 Electrical Features of the U InterfaceThis section describes the electrical features of the U interface.

A.2.1 OverviewThis section describes the definition of the U interface.

U interface (also known as 2 binary 1 quaternary, which is 2B1Q) is the interface of networktermination 1 (NT1) and line termination (LT) in ISDN reference model.

In terms of code pattern, since subscriber line features are different in different countries, theirline code patterns also vary. For instance, North America and China use 2B1Q code, Japan andItaly adopt AMI, while UK adopts 3B2T code. ITU-T has no recommended uniform transmissionmode and line code pattern for 2B+D U interface.

The following description is only applicable to 2B1Q code pattern.

A.2.2 Basic Features of the U InterfaceThis section describes the basic features of the U interface.

l Line code

Line code is 2B1Q (2-bit binary code is expressed with 1-bit quaternary code). This is a 4-levelnon-redundancy code.

l Line baud rate: 80 kbit/s

l Clock tolerance

The tolerance of free-run NT1 clock is ±100 ppm.

The tolerance of LT clock is ±5 ppm.

l Frame structure

A primary frame should be the 120 quaternary signals transmitted with nominal 1.5 ms interval.A primary frame includes frame bit, 2B+D data bit and connection line (CL) channel bit. 8primary frames (12 ms in total) form a multi-frame.

A.2.3 Specifications and Program of the U InterfaceThis section describes the specifications and program of the U interface.

The following is the bit allocation and function of multi-frame based on G.961 specification.



Monitoring Function of CRC Bit Error

Bits M5 and M6 of the 3rd frame and 8th frame of each multi-frame comprise the CRC, whichare inserted into bit flow through transmitter. In receiver, the CRC bit calculated from the samebits should be compared with the received CRC. If they are different, it indicates that there is atleast one bit error in the multi-frame.

EOC Frame Function

In each multi-frame, the EOC in DS1 rate interface consists of 24 bits. It implements thecommunication between the network and NT1. The following basic functions are required forthe EOC:

l Operation of 2B+D loopback: This function commands NT1 to loop back the subscriberdata bit stream toward the network.

l Operation of B1 (or B2) channel loopback: This function requires NT1 to setup single Bchannel loopback toward the network. Single B channel loopback can provide maintenanceon this channel and the subscriber services are not totally blocked.

l Recovery to normal: This message is used to release all the uncompleted EOC controlledoperation, and reset the EOC message processor to its initial state.

l Unfollowable acknowledgement: This message acknowledges that NT1 has received anEOC message, but it is not in the menu of NT1.

l Request degraded CRC notification: This message requests to send degraded CRC towardthe network.

l Degraded CRC notification: This message informs NT1 that the intentionally degradedCRC will be sent from the network till there is a "Recovery to normal" message.

l Hold state

A.2.4 Activation and Deactivation of the U InterfaceThis section describes how to activate and deactivate the U interface.

Activation

ITU-T Recommendation G.961 defines the signals generated by transceiver during startup.These signals are used in two start types: cold start and hot start. When NT1 and LT are in theresetting state, the activation is allowed either from the subscriber equipment or from thenetwork. The initiator sends single tone in compliance with ITU-T Recommendation G.961 andstarts activation process. In cold start mode, LT and NT1 should complete the synchronizationwithin 15 seconds, with 5 seconds for NT1 and 10 seconds for LT; while in hot start mode, theyshould complete the synchronization within 300 ms.

Deactivation

When one of the following happens, the transceiver is allowed to enter the reset state.

l The system cannot be started within 15 seconds (hot or cold start).

l The received signal is lost for more than 480 ms.

l Synchronization is lost for more than 480 ms.


Product Description


A.2.5 Electrical Features of the U InterfaceThis section describes the electrical features of the U interface.

Output PulseThe nominal peak value of output pulse is 2.5 V. The pulse shape should be as shown in FigureA-9 and four-quaternary-characters pulse sample should be obtained from the nominal sampleas shown in Figure A-9 multiplied by 2.5 V, 0.83 V, –0.83 V or –2.5 V.
