Port Adapter OverviewThe PA-MC-8TE1+ (see Figure 1-1) is a single-wide port adapter that provides eight T1 or E1 interfaces. The PA-MC-8TE1+ interfaces can be channelized, fractional, or unframed (E1 only).

Figure 1-1 PA-MC-8TE1+ Port Adapter—Faceplate View

Channelized T1/E1 OverviewWhen you are running channelized data, each DS1 interface can provide up to 24 T1 channel groups if your PA-MC-8TE1+ is configured for T1, or 31 E1 channel groups if your PA-MC-8TE1+ is configured for E1. The T1 groups are numbered from 0 to 23 and the E1 groups are numbered from 0 to 30. Each T1 channel group provides up to twenty-four 64-kbps time slots, which are numbered 1 to 24. Each E1 channel group provides up to thirty-one 64-kbps time slots, which are numbered 1 to 31. Multiple time slots can be mapped to a single channel group. Each channel group is presented to the system as a serial interface that can be configured individually. Usable bandwidth for each channel group is calculated as n x 56 kbps or n x 64 kbps, where n is the number of T1 time slots (1 to 24) or E1 channels (1 to 31).

1-1/E1 PRI Port Adapter Installation and Configuration

Chapter 1 Overview Features

When you are running ISDN PRI, each T1 interface provides 23 bearer (B) channels that can transmit and receive data at the rate of 64 kbps, full-duplex, and one data (D) channel that can transmit and receive data at the rate of 64 kbps, full-duplex. Each E1 interface provides 30 bearer (B) channels that can transmit and receive data at the rate of 64 kbps, full-duplex, and one data (D) channel that can transmit and receive data at the rate of 64 kbps, full-duplex. The B channels are used for transmitting user data. The D channel is used for call setup control and network connection teardown, and provides the communication from the router to the ISDN switch. The B and D channels are presented to the system as serial interfaces that support High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) encapsulation. The multichannel PA-MC-8TE1+ port adapter supports dial-on-demand routing (DDR) when you are running ISDN PRI.

Note The PA-MC-8TE1+ does not support ISDN PRI when installed in the FlexWAN module.

Each of the channels on the PA-MC-8TE1+ uses a portion of the bandwidth (fractional T1 or E1) or the entire bandwidth for data transmission. Usable bandwidth for each channel is n x 56 kbps or n x 64 kbps, where n is a number from 1 to 24 for T1 and 1 to 31 for E1. When you are not running at full T1 and E1 speeds, the unused portion of the bandwidth cannot be used and is filled with idle channel data.

Note Time slots on the PA-MC-8TE1+ are numbered 1 to 24 for T1 and 1 to 31 for E1, instead of the zero-based scheme (0 to 23 or 0 to 30) used with other Cisco products. This numbering scheme is to ensure consistency with telco numbering schemes for T1 and E1 channels within channelized equipment.

The PA-MC-8TE1+ supports Facility Data Link (FDL) in Extended Superframe (ESF) framing on T1 networks, as well as network and payload loopbacks. Bit error rate testing (BERT) is supported on each of the T1 or E1 links.

Note On a PA-MC-8TE1+, BERT is done over only a framed T1/E1signal.

The PA-MC-8TE1+ does not support the aggregation of multiple T1s or E1s (called inverse muxing or bonding) for higher bandwidth data rates. The multichannel PA-MC-8TE1+ supports Cisco HDLC, Frame Relay, PPP, and Switched Multimegabit Data Service (SMDS) Data Exchange Interface (DXI) encapsulations over each T1 or E1 link. For SMDS only, DXI is sent on the T1 or E1 line, so it needs to connect to an SMDS switch that has direct DXI input.

FeaturesThe PA-MC-8TE1+ provides the following features:

• NxDS0 BERT capability allowing BERT to run on per channel/timeslot basis (NxDS0 BERT is an extension of the existing BERT functionality allowing BERT testing on a per DS0 basis)

• Universal ports—Eight interface ports per port adapter are configurable as either T1 (with integrated channel service unit [CSU] and data service unit [DSU]) or E1 (with integrated G.703/G.704 balanced 120-ohm interface)

• Full DS0 channelization capability for all T1/E1 ports, for a maximum of 248 full-duplex HDLC channels

• Data rates in multiples of 56 kbps or 64 kbps per channel

• Maximum data rates per port:1.536 Mbps (T1), 1.984 Mbps (E1 G.704), 2.048 Mbps (E1 unframed)

Chapter 1 Overview Restrictions

• Integrated T1/E1, supporting line code alternate mark inversion (AMI), binary 8-zero substitution (B8SZ) for T1 circuits, framing AMI or high-density binary 3 (HDB3) for E1 circuits, framing Super Frame (SF) or Extened Superframe (ESF) for T1 circuits, CRC4, and no-CRC4 or unframed for E1 circuits

• Full Facility Data Link (FDL) support and FDL performance monitoring per ANSI T1.403 or AT&T TR 54016

• Full ISDN support for either 23B+D (T1) or 30B+D via network processing engine (NPE)

Note The PA-MC-8TE1+ does not support ISDN PRI when installed in the FlexWAN module.

• Performance monitoring

• Alarm integration, detection, and insertion

• Line and payload loopback on a per-DS0 level

• Clock jitter attenuators

• Line or internal clocking

RestrictionsThe following restrictions apply when you are using a Cisco 7500 series or Cisco 7600 series router.

• The PA-MC-8TE1+ does not support ISDN PRI when installed in the FlexWAN module.

• When the PA-MC-8TE1+ is installed in a VIP in a Cisco 7500 series router, a memd recarve is triggered after the card type command. The system locks up for 3 minutes while the memory is recarved.

Note This condition occurs only with an image that does not incorporate CSCec11122.

LEDsThe PA-MC-8TE1+ has a green enabled (EN) LED, a bicolor alarm (AL) LED, and bicolor port status LEDs for each port on the port adapter (see Figure 1-2).

Chapter 1 Overview Cables, Connectors, and Pinouts

After system initialization, the EN LED comes on to indicate that the port adapter has been enabled for operation.

The following conditions must be met before the PA-MC-8TE1+ is enabled:

• The PA-MC-8TE1+ is correctly connected and is receiving power.

• A valid system software image for the port adapter has been downloaded successfully.

• The system recognizes the PA-MC-8TE1+.

If any of the above conditions are not met, or if the initialization fails for other reasons, the EN LED does not come on.

Table 1-1 lists the functions of the LEDs.

Cables, Connectors, and PinoutsThe T1/E1 interface receptacles on the PA-MC-8TE1+ are RJ-48C connectors for both T1 (100 ohm) and E1 (120 ohm).

After you properly connect a port to a line, it takes approximately 30 seconds for Cisco IOS to report that the line is up.

Each connection supports T1 (100-ohm) or E1 (120-ohm) interfaces that meet T1.403 and ACCUNET TR62411 standards. The RJ-48C connector does not require an external transceiver. The DS1 ports are T1 interfaces that use foil twisted-pair (FTP) cables.

Shielded FTP cables with 120-ohm impedance are required to comply with CE marking requirements.

Figure 1-3 shows the PA-MC-8TE1+ interface cable connector. See the “Connecting Interface Cables” section on page 3-12 for directions on connecting the cables to a PA-MC-8TE1+.

Chapter 1 Overview Identifying Interface Addresses

Identifying Interface Addresses This section describes how to identify interface addresses for the PA-MC-8TE1+ in the supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a PA-MC-8TE1+ installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-MC-8TE1+ installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move the VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot.

Note Interface ports are numbered from left to right starting with 0.

The following subsections describe the interface address formats the supported platforms:

• Cisco 7200 and Cisco 7200 VXR Series Routers Interface Addresses, page 1-20

• Cisco 7201 Router Interface Addresses, page 1-20

• Cisco 7301 Router Interface Addresses, page 1-20

• Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses, page 1-21

• Cisco 7401ASR Router Interface Addresses, page 1-21

• Cisco 7500 Series Routers VIP Interface Addresses, page 1-21

• Catalyst 6000 Family Switches and Cisco 7600 Series Routers with FlexWAN Module Interface Addresses, page 1-22

Table 1-3 summarizes the interface address formats for the supported platforms.

Cisco 7200 and Cisco 7200 VXR Series Routers Interface Addresses In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-4, Figure 1-5, Figure 1-6, and Figure 1-7.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if an eight-port PA-MC-8TE1+ is installed in slot 3 of a Cisco 7200 series router, the interface addresses would be 3/0 through 3/7 (port adapter slot 3 and interfaces 0 through 7).

Cisco 7201 Router Interface AddressesIn the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-8.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if an eight-port PA-MC-8TE1+ is installed in a Cisco 7201 router, the interface addresses would be 1/0 through 1/7 (port adapter slot 1 and interface port 0 through interface port 7).

Cisco 7301 Router Interface AddressesIn the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-9.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if an eight-port PA-MC-8TE1+ is installed in a Cisco 7301 router, the interface addresses would be 1/0 through 1/7 (port adapter slot 1 and interface port 0 through interface port 7).

2. Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.

Table 1-3 Identifying Interface Addresses (continued)

Platform Interface Address Format Numbers Syntax


OL-2738-07


Cisco 7304 PCI Port Adapter Carrier Card Interface AddressesIn the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-10 and Figure 1-11.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1-3. For example, if an eight-port PA-MC-8TE1+ is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface addresses would be 3/0 through 3/7 (port adapter slot 3 and interface port 0 through interface port 7).

Cisco 7401ASR Router Interface AddressesIn the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if an eight-port PA-MC-8TE1+ is installed in a Cisco 7401ASR router, the interface addresses would be 1/0 through 1/7 (port adapter slot 1 and interface port 0 through interface port 7).

Cisco 7500 Series Routers VIP Interface AddressesIn Cisco 7000 series routers and Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-13, Figure 1-14, Figure 1-15, and Figure 1-16.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-3.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-MC-8TE1+ is an eight-port port adapter, therefore the port can be 0 through 7.

For example, if an eight-port PA-MC-8TE1+ is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface addresses would be 3/1/0 through 3/1/7 (interface processor slot 3, port adapter slot 1, and interfaces 0, 1, 2, 3, 4, 5, 6, and 7).

Note Although the processor slots in the seven-slot Cisco 7507 and thirteen-slot Cisco 7513 and Cisco 7576 are vertically oriented and those in the five-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series routers use the same method for slot and port numbering.

Catalyst 6000 Family Switches and Cisco 7600 Series Routers with FlexWAN Module Interface Addresses

In Catalyst 6000 family switches and Cisco 7600 series routers, port adapters are installed in a FlexWAN module, which installs in module slots 2 through 13 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the FlexWAN module. See Figure 1-17, Figure 1-18, Figure 1-19, Figure 1-20, and Figure 1-21.

The interface address is composed of a three-part number in the format module-slot-number/port-adapter-bay-number/interface-port-number. See Table 1-3.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1. The Cisco 7609 is the exception with slots numbered right to left, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-MC-8TE1+ is an eight-port port adapter, therefore the port can be 0 through 7.

For example, if an eight-port PA-MC-8TE1 is installed in the FlexWAN module, which is inserted in module slot 3, port adapter bay 0, the interface addresses would be 3/0/0 through 3/0/7 (module slot 3, port adapter slot 0, and interfaces 0, 1, 2, 3, 4, 5, 6, and 7). If the same port adapter is in port adapter bay 1 on the FlexWAN module, the interface addresses would be 3/1/0 through 3/1/7 (module slot 3, port adapter slot 1, and interfaces 0, 1, 2, 3, 4, 5, 6, and 7).

Note The FlexWAN module physical port address begins with slot 0, which differs from the conventional Catalyst 6000 family port address, which begins with slot 1.
