Port Adapter Overview

The multichannel E1/PRI port adapters (PA-MC-2E1/120 and PA-MC-8E1/120) integrate data service unit (DSU) functionality and E1 channel support into the Cisco router.

The PA-MC-2E1/120 and PA-MC-8E1/120 provide two or eight independent E1 (120-ohm) connections via RJ-48C connectors. (See Figure 1-1 and Figure 1-2.) The PA-MC-8E1/120 can provide up to 128 separate full-duplex High-Level Data Link Control (HDLC) channelized E1, fractional E1, full E1, or unframed E1 interfaces and the PA-MC-2E1/120 can provide up to 62 separate full-duplex HDLC channelized E1, fractional E1, full E1, or unframed E1 interfaces.


Note The Catalyst RSM/VIP2 and the Catalyst 6000 family FlexWAN module support the PA-MC-8E1/120 multichannel E1/PRI port adapter only.



Note The Cisco 7201 router supports the PA-MC-2E1/120 multichannel E1/PRI port adapter only.



Note The Cisco 7401ASR router supports the PA-MC-8E1/120 multichannel E1/PRI port adapter only.

Figure 1-2 PA-MC_8E1/120 Port Adapter Front-Panel View


Note Each port adapter has a handle attached, but this handle is not shown in this publication to allow a full view of the detail on the port adapter face plate.


When you are running channelized E1, each E1 interface can provide up to 31 E1 channel groups, which are numbered from 0 to 30. Each channel group provides up to 31 64-kbps timeslots (E1 channels), which are numbered 1 to 31. Multiple timeslots 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 a number of E1 channels (1 to 31).


Note The Catalyst 6000 family FlexWAN module does not support ISDN.


When you are running ISDN PRI, 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 HDLC and Point-to-Point Protocol (PPP) encapsulation. The multichannel E1/PRI port adapter supports dial-on-demand routing (DDR) when you are running ISDN PRI.

Each of the E1 channels on the multichannel E1/PRI port adapter uses a portion of the E1 bandwidth (fractional E1) or the entire E1 bandwidth for data transmission. Usable bandwidth for each E1 is n x 64 or n x 56 kbps, where n is a number from 1 to 31. The unused portion of the E1 bandwidth, when you are not running at full E1 speeds, cannot be used and is filled with idle channel data.


Note E1 timeslots on the PA-MC-2E1/120 or PA-MC-8E1/120 are numbered 1 to 31, rather than following the more traditional zero-based scheme (0 to 30) used with other Cisco products. This is to ensure consistency with telco numbering schemes for E1 channels within channelized equipment.


The PA-MC-2E1/120 or PA-MC-8E1/120 support network and payload loopbacks. Bit error rate (BER) testing is supported on each of the E1 links. The bit error rate (BER) tester can be run only on one port at a time.

The PA-MC-2E1/120 or PA-MC-8E1/120 supports the aggregation of multiple E1s (called inverse multiplexing or bonding) for higher bandwidth data rates. The PA-MC-2E1/120 or PA-MC-8E1/120 also supports Cisco HDLC, Frame Relay, PPP, and SMDS Data Exchange Interface (DXI) encapsulations over each E1 link. For SMDS only, DXI is sent on the E1 line, so it needs to connect to an SMDS switch that has direct DXI input.

Both port adapters:

20 with Cisco IOS 11.2 release and Cisco IOS 11.1CA release


Rules for determining the allowable number of PRI groups per port adapter:

Each port can have a maximum of 1 PRI group

Each PRI group can have from 1-31 timeslots configured

The number of channels is determined adding the number of timeslots (B channels) configured, and the 1 required D channel (per PRI group)

The allowable number of PRI groups per port adapter is governed by the maximum number of channels supported by the hardware which is 128

Example 1: Valid configuration.

PA-MC-8E1 configured with:

1 PRI group of 10 timeslots (10 B channels + 1 D channel = 11 channels)
1 PRI group of 20 timeslots (20 B channels + 1 D channel = 21 channels)
1 PRI group of 15 timeslots (15 B channels + 1 D channel = 16 channels)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 channels)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 channels)
Total number of channels: 110

This example is valid because 110 channels is fewer than the 128 channels maximum allowable per port adapter. In this case the 5 PRI ports can be used for the PA-MC-8E1. (Another 18 channels could be configured for a maximum of 128 [110 + 18 = 128] ports.)

Example 2: Non-valid configuration.

PA-MC-8E1 configured with:

1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 interfaces)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 interfaces)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 interfaces)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 interfaces)
1 PRI group of 31 timeslots (30 B channels + 1 D channel = 31 interfaces)
Total number of interfaces: 155

This example is not valid because 155 channels exceeds the 128 channels allowable.

LEDs

The multichannel E1/PRI port adapter contains the ENABLED LED, standard on all port adapters, and one status LED for each port. After system initialization, the ENABLED LED goes on, indicating that the multichannel E1/PRI port adapter has been enabled for operation. (See Figure 1-3 and Figure 1-4.) The console screen also displays a message as the system discovers each interface during its reinitialization.

The following conditions must be met before the multichannel E1/PRI port adapter is enabled:

The multichannel E1/PRI port adapter is correctly connected to the backplane and receiving power.

The system bus recognizes the multichannel E1/PRI port adapter.

A valid version of multichannel E1/PRI port adapter microcode is loaded and running.

If any of these conditions is not met, or if the initialization fails for other reasons, the ENABLED LED does not go on.

Cables, Connectors, and Pinouts

The E1/PRI interface receptacles on the multichannel E1/PRI port adapter are RJ-48C receptacles for E1 (120-ohm). You can use them all simultaneously. Each connection supports E1 (120-ohm) interfaces that meet G.703 standards. The RJ-48C connection does not require an external transceiver. The E1/PRI ports are E1 interfaces that use 120-ohm unshielded twisted pair cables. (See Figure 1-5.)


Note To meet VCCI Class II EMI requirements, you must use foil twisted pair (FTP) cables.


Figure 1-5 and Table 1-4 show the multichannel E1/PRI port adapter interface cable, connector, and pinout.

The Cisco 7513 router is not shown.

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-MC-2E1/120 or PA-MC-8E1/120 in the supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a PA-MC-2E1/120 and PA-MC-8E1/120 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-2E1/120 and PA-MC-8E1/120 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 a 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.



Note E1 timeslots on the multichannel E1/PRI port adapter are numbered 1 to 31, rather than following the more traditional zero-based scheme (0 to 30) used with other Cisco products. This is to ensure consistency with telco numbering schemes for E1 channels within channelized E1 equipment.

1 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.

2 Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).


Catalyst RSM/VIP2 Interface Addresses

In Catalyst 5000 family switches, the Catalyst RSM/VIP2 can be installed in any slot except the top slots, which contain the supervisor engine modules. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch does not use interface processor slot numbering; therefore, the slots in which it is installed are not numbered. A port adapter can be installed into either port adapter slot 0 or slot 1 on a Catalyst RSM/VIP2. See Figure 1-6.

The interface address is composed of a three-part number in the format port-adapter-slot number/interface-port number:channel-group-number. See Table 1-5. For example, if an eight-port PA-MC-8E1/120 is installed in slot 1, channel 1, on a Catalyst RSM/VIP2, the interface addresses would be 1/0:1, 1/1:1, 1/2:1, 1/3:1, 1/4:1, 1/5:1, 1/6:1, and 1/7:1 (port adapter slot 1 interface ports 0 through 7, and channel group 1).


Note The Catalyst RSM/VIP2 supports the PA-MC-8E1/120 only.


Catalyst 6000 Family FlexWAN Module Interface Addresses

The Catalyst 6000 family FlexWAN module can be installed in module slots 2 through 13 (depending on the number of slots in the router). Slot 1 is reserved for the supervisor engine. A port adapter can be installed into either port adapter bay 0 or bay 1 on a FlexWAN module. See Figure 1-7.

The interface address is composed of a four-part number in the format module-number/ port-adapter-bay-number/interface-port-number:channel-group-number. See Table 1-5.

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 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-8E1/120 is an eight-port port adapter, therefore the port can be 0 through 7.

The fourth number identifies the logical channel group and is a number from 0 through 30.

For example, if an eight-port PA-MC-8E1/120 is installed in the FlexWAN module in module slot 3, port adapter bay 0, channel 1, the interface addresses would be 3/0/0:1 through 3/0/7:1 (module slot 3, port adapter bay 0, interface ports 0 through 7, and channel group 1).


Note The FlexWAN module supports the PA-MC-8E1/120 only.



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.


Cisco 7100 Series Routers Interface Addresses

In Cisco 7120 series router, port adapters are installed in port adapter slot 3. See Figure 1-8. In the Cisco 7140 series router, port adapters are installed in port adapter slot 4. See Figure 1-9.

The interface address is composed of a three-part number in the format port-adapter-slot-number/interface-port-number:channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed on channel 1 of a Cisco 7120 router, the interface addresses would be 3/0:1 and 3/1:1. If a dual-port PA-MC-2E1 is installed on a Cisco 7140 router, the interface addresses would be 4/0:1 and 4/1:1.

Cisco 7200 Series and Cisco uBR7200 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 2 for the Cisco 7202, 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 1-10.

The interface address is composed of a three-part number in the format port-adapter-slot-number/interface-port-number: channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed in slot 1, channel 1, on a Cisco 7200 series router, the interface addresses would be 1/0:1 and 1/1:1. If an eight-port PA-MC-8E1/120 is installed in slot 1, channel 1, on a Cisco 7200 series router, the interface address would be 1/0:1, 1/1:1, 1/2:1, 1/3:1, 1/4:1, 1/5:1, 1/6:1, and 1/7:1 (port adapter slot 1 interface ports 0 through 7, and channel group 1).

Cisco uBR7200 Series Routers Interface Addresses

In the Cisco uBR7223 router, only one slot accepts port adapters and it is numbered slot 1.

In the Cisco uBR7246 router and Cisco uBR7246VXR router, port adapters can be installed in two port adapter slots (slot1 and slot 2). Slot 0 is always reserved for the I/O controller—if present. See Figure 1-11.

The interface address is composed of a three-part number in the format port-adapter-slot-number/interface-port-number: channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed in channel 1 of a Cisco uBR7223 router, the interface addresses would be 1/0:1 and 1/1:1 (port adapter slot 1 interface ports 0 and 1, and channel group 1). If an eight-port PA-MC-8E1/120 is installed slot 2, channel 1, of a Cisco uBR7246 router, the interface addresses would be 2/0:1, 2/1:1, 2/2:1, 2/3:1, 2/4:1, 2/5:1, 2/6:1, and 2/7:1 (port adapter slot 2 interface ports 0 through 7, and channel group 1).

Cisco 7201 Router Interface Address

In the Cisco 7201 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 three-part number in the format port-adapter-slot-number/interface-port-number:channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed on channel 1 of a Cisco 7201 router, the interface addresses would be 1/0:1 and 1/1:1 (port adapter slot 1 interface ports 0 and 1, and channel group 1).


Note The Cisco 7201 router supports the PA-MC-2E1/120 only.


Cisco 7301 Router Interface Address

In the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-13.

The interface address is composed of a three-part number in the format port-adapter-slot-number/interface-port-number:channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed on channel 1 of a Cisco 7301 router, the interface addresses would be 1/0:1 and 1/1:1 (port adapter slot 1 interface ports 0 and 1, and channel group 1). If an eight-port PA-MC-8E1/120 is installed on channel 1 of a Cisco 7301 router, the interface addresses would be 2/0:1, 2/1:1, 2/2:1, 2/3:1, 2/4:1, 2/5:1, 2/6:1, and 2/7:1 (port adapter slot 2 interface ports 0 through 7, and channel group 1).

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

In 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 1-14 and Figure 1-15.

The interface address is composed of a three-part number in the format module-slot-number/interface-port-number:channel-group-number. See Table 1-5. For example, if a dual-port PA-MC-2E1/120 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, channel 1, the interface addresses would be 3/0:1 and 3/1:1 (port adapter slot 3 interface ports 0 and 1, and channel group 1). If an eight-port PA-MC-8E1/120 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface addresses would be 3/0:1, 3/1:1, 3/2:1, 3/3:1, 3/4:1, 3/5:1, 3/6:1, and 3/7:1 (port adapter slot 3 interface ports 0 through 7, and channel group 1).

Cisco 7401ASR Router Interface Addresses

In the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-16.

The interface address is composed of a three-part number in the format port-adapter-slot-number/interface-port-number:channel-group-number. See Table 1-5. For example, if an eight-port PA-MC-8E1/120 is installed on channel 1 of a Cisco 7401ASR router, the interface addresses would be 2/0:1, 2/1:1, 2/2:1, 2/3:1, 2/4:1, 2/5:1, 2/6:1, and 2/7:1 (port adapter slot 2 interface ports 0 through 7, and channel group 1).


Note The Cisco 7401ASR router supports the PA-MC-8E1/120 only.


Cisco 7000 Series Routers and Cisco 7500 Series Routers VIP Interface Addresses

In 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 1-17, and Figure 1-18.

The interface address for the VIP is composed of a four-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port- number:channel-group-number. See Table 1-5.

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-2E1/120 is a dual-port port adapter, therefore the port can be 0 or 1. The PA-MC-8E1/120 are eight-port port adapters, therefore their port can be 0 through 7.

The fourth number identifies the logical channel group and is a number from 0 through 30.

For example, if a dual-port PA-MC-2T1 is installed in a VIP in interface processor slot 3, port adapter slot 1,channel 1, the interface addresses would be 3/1/0:1 and 3/1/1:1 (interface processor slot 3, port adapter slot 1, interface ports 0 and 1, and channel group 1). If an eight-port PA-MC-8E1/120 is installed in a VIP in interface processor slot 3, port adapter slot 1, channel 1, the interface addresses would be 3/1/0:1, 3/1/1:1, 3/1/2:1, 3/1/3:1, 3/1/4:1, 31//5:1, 3/1/6:1, and 3/1/7:1 (interface processor slot 3,port adapter slot 1, interface ports 0 through 7, and channel group 1).


Note Although the processor slots in the seven-slot Cisco 7000 and Cisco 7507 routers and the thirteen-slot Cisco 7513 router are vertically oriented and those in the five-slot Cisco 7010 and Cisco 7505 routers are horizontally oriented, all Cisco 7000 series and Cisco 7500 series routers use the same method for slot and port numbering.
