PRBS generator/analyzer: all disabled

3.2 Configuration Modes

3.2.1 Loop Back Mode

The EtherMate provides four types of loopback : Remote E1 Line Loopback,

Remote MII Loopback, Local E1 Loopback Toward MII, Local MII Loopback.

(Please refer to Figure 3-1-1.1).

Special care should be taken: users should avoid to do Remote T1/E1 Line

Loopback for all useable channels, otherwise the Remote Management (HDLC

channel) may disrupt due to no available E1 channel for in-band control.

Figure 3-1-1.1 Loopback Mode of EtherMate


Page 13 of 30

3.2.2 E1 PRBS Generator and Analyzer

The EtherMate supports three types of PBRS (2^15-1, 2^20-1 and 2^23-1) for

analyzing E1 payload. PRBS generation on any E1 channel will cause the channel

to be unused (be removed) but it will not impact normal Ethernet traffic on other E

links. The PRBS analysis is a monitoring scheme and there is no impact on normal

traffic. Users can used this feature to check the mapping of E1 pair between local

and remote site.

3.2.3 IP Configuration

The IP address of management port (MNT) can be setup thru RS232. After change

the IP address for local node or remote node, the current configuration of relative

EtherMate (either local or remote) will be saved (same as key-in csave command

in CLI interface) as well as re-booted the system.

3.2.4 HDLC Target

To do remote control, users should specify HDLC ID and then assign Near-end

HDLC ID and Far-end HDLC IC for local node and remote node respectively.

3.3 Provision Modes

3.3.1 Ethernet Type (10/100M, Auto-Negotiation)

The Ethernet interface of EtherMate can be manually configured as 10 BASE-T

Full-Duplex, 100-BASE-TX or Auto-Negotiation. The default setup is in

auto-negotiation mode. When the EtherMate is configured to Auto-negotiation

mode, it may interconnect with device without auto negotiation; in this case, the

EtherMates PHY is required to establish link at Half-Duplex mode only (refer to

IEEE 802.3 clauses 28 and 40 for detail). Although the Ethernet PHY of EtherMate is

forced to half-duplex, the EtherMates MAC can only support full-duplex mode. The

link status of EtherMate may show that EtherMate is operated in half-duplex mode,

the Ethernet traffic can still active until collision occurs. While the EtherMate is

operated for point-to-point, collision will not taken place; users can ignore the

message of half-duplex mode.

3.3.2 E1 CRC4 Mode

The E1 framing of EtherMate can be programmed as no-CRC4 mode or CRC4

mode depending the network configuration. If CRC4 mode is to enable the E1

framing should declare framing lock upon synchronization of CRC4 multi-frame.

Since the remote management (HDLC channel) of EtherMate is in-band, to keep the


Page 14 of 30

HDLC channel alive, all E1 channel should not fail simultaneously. When users

trying to change CRC4 mode thru remote management channel the HDLC channel

may croup when the CRC4 mode at local site is mismatching with that of remote

site.

Users should change remote site first to prevent from break-down on remote

management channel. Please see the note2 of Table 3-3.1 (CLI Command

Description) for cautions.

3.3.3 Virtual Concatenation (H4) Mode

The EtherMate implements two kinds of virtual concatenation algorithms to

de-assemble and re-assemble the Ethernet traffic into/from multiple E1. The virtual

concatenation (H4) can be ITU-T standard (per G.8040/G.7043) or Proprietary.

According to ITU-T standards, the control bytes of virtual concatenation are

synchronized with E1 CRC4 multiframe. As this, the standard H4 mode can only

be enabled when CRC4 mode is active. To minimize the recovery time (packet

re-synchronization) during bandwidth adjustment, one can chose Proprietary mode

with a penalty of bandwidth degrading.

3.3.4 E1 CAS Mode (PCM30)

The E1 CAS (Channel Associate Signaling) mode refer to PCM30. It depict that time

slot 16 (signaling channel) is unequipped (ie., it is unable to carry GFP/Ethernet

traffic). When the CAS mode is enable, the EtherMate do not carry signaling in time

slot16 but it just skip to carry payload in this time lot. This mode is provided so that

EtherMate can pass those PDH networks supported only PCM30. CAS disable

(PCM31) is the default setting such as the EtherMate can have better through put

(more bandwidth).

3.3.5 Link Loss Carry Forward (LLCF)

The EtherMate provide LLCF mode so that local switch/router interconnected with

EtherMate can detect remote link failure by shutting down the local link during

remote failure. The scenario of LLCF mode is shown on Figure 3-2-5.1.

As illustrated on Figure 3-2-5.1, the EtherMate-A detects link down and send client

failure signal to EtherMate-B. The EtherMate-B will shut down its Ethernet link so

that switch/router connected with EtherMate-B can detect link failure.1 By default

this mode is disable.


Page 15 of 30

Figure 3-2-5.1 Application of LLCF

3.3.6 E1 Auto Bandwidth Adjustment

The number of active E1 channel (equipped with GFP/Ethernet) can be adjusted

manually or automatically. When it is operated in manual mode, users should select

which channel to be active or inactive depending on the alarm status. Alternatively,

when it is operated in auto mode, the EtherMate will automatically adjust the E1

bandwidth according to E1 link status and H4 synchronization-state. However, users

still can shut down unused E1 channels (even there is no alarm on these channel)

while EtherMate is operated in auto mode. The default setting is auto mode.

3.3.7 Alarm Suppression Configuration

By default, any error on an E1 link will be reported to CPU and trigger E1 LED even

it is shut down by users. The EtherMate provide an option to suppress the E1 alarms

& LED for those unused E1 links.

3.3.8 LCAS

With LCAS (Link Capacity Adjustment Scheme), operator can increase or decrease

the total bandwidth provided for Ethernet without hit while the whole system is under

service. This flexibility gives service provider a better way to dynamically adjust

bandwidth according to customers need.

3.3.9 Fault Report

The alarms/status of near-end or far-end node can be reported thru RS232 (CLI

command) or SNMP-based management.

T1/E1 interface: is 100 Ohm/120 Ohm via RJ45 connectors.

DS3 interface: is a pair of 75ohm BNC connectors for TX and RX.

(2) AC Power Socket and Switch (On/Off switch for AC):

The power module provides the power with AC 110 ~ 240V

(3) DC Adaptor (5V):

Power cable of DC adaptor from AC 110~240V to DC 5V is optionally provided by

customer requirement.

(4) Timing Mode Selection Switch

A DIP-switch selection provides the transmitting timing source for T1/E1/DS3 interfaces

as two kinds of LINE and INT (internal) modes. The transmitting timing of T1/E1/E3/DS3

can be sourced either from local oscillator (internal timing) or receive side (line timing).

The timing accuracy of the local oscillator is within +/- 20ppm. For multiple E1/T1

modules operated in line timing mode, the EtherMate will automatically select the

recovered clock of active channel as transmitted clock according to port priority (port-1 is

the highest priority and port-8 is the lowest priority).

3.5 Hyper-Terminal Setup

Note1 : EtherMate only support full-duplex mode but it can report the duplex status of connected object to

identify the link failure caused by missing type (i.e. half-duplex connects to full-duplex)

Note2 : The switching of CRC-4 mode should be carefully, otherwise the E1 links between local and

remote site will be broken. Subsequently, the in-band remote management channel (HDLC)

may crash. Please follow the following procedures to change CRC-4 mode smoothly:

(I). Change CRC4 enables to disable:

setup RT (Remote Terminal) first so that RT site (without CRC-4) still can lock the

framing and receive HDLC command from local terminal (with CRC-4). After then

disabling the CRC-4 mode of local site

(II). Change CRC4 mode from disable to enable:

setup RT (Remote Terminal) first so that the CRC-4 mode of RT site can be changed

before in-band HDLC management channel is broken. After changing the CRC-4

mode of RT site the local node may temperately unable to get remote status due to

loss of CRC-4 multi-frame in remote site. The management channel can be

recovered after change the CRC-4 mode of local site.

Note3 : work only in manual mode.
