Port Adapter Overview

The P A-4E1G, sho wn in Figure 1-1 and Figure 1-2, provides up to four E1 synchronous serial interfaces, which are compatible with and specified by G.703/G.704. The PA-4E1G network interfaces provide a connection between standard serial interfaces such as V.35 to telephone lines or Post, Telephone, and Telegraph (PTT) networks. Each PA-4E1G interface operates in full-duplex mode at E1 (2.048 Mbps) speed.

The PA-4E1G interfaces do not operate in the data terminal equipment (DTE) and data communications equipment (DCE) modes that are typical of data communications interfaces. The PA-4E1G interfaces operate with either a line-recovered or an internal clock signal. The def ault is fo r a line clock si gnal th at the interface recovers from the received data stream. The interface can also operate with an internal clock signal. The PA-4E1G generates the internal clock signal; the interface does not use the motherboard or system clock.

The PA-4E 1G provides the following features and capabilities:

• Provides framed and unframed service access, E1 (2.048 Mbps) line speeds over unbalanced 75-ohm

or balanced 120-ohm cable, with 15-pin, D-shell (DB-15) receptacles on the port adapter

• Operates over E1 leased-line services, and provides ITU-T G.703 with high-density bipolar of order

3 (HDB3) line encoding

• Operates with either an external or internal clock signal, and runs at wire speed

• Provides for local and remote loopback testing services

• Allows you to fractionalize a data stream into a single channel from 64 kilobits per second (kbps)

to 1984 kbps

• Provides G.704 framing for n x 64-kbps service support (where n = 1 to 31)

• Support for 4-bit cyclic redundancy check (CRC4) to provide and ensure data integrity

• Support for point-to-point connections to supported platforms

• Eliminates the need for a separate, external data termination unit that is typically used to convert

standard serial interfaces, such as V.35, to E1-G.703/G.704

Note PA-4E 1Gs are available as spare parts PA-4E1G-120(=) and PA-4E1G-75(=).

Interface Specifications

Each PA-4E1G interface is available in either balanced (120-ohm) or unbalanced (75-ohm) mode; a unique port adapter supports each type. Neither the balanced and unbalanced modes nor the balanced and unbalanced cables are interchangeable; you cannot configure a balanced port to support an unbalanced line, nor can you attach an interface cable intended for a balanced line to an unbalanced port.

Balanced interfaces typically use three conductors and three signal states: high, low, and ground. The high and low signals mirror each other. Unbalanced interfaces use only two signals: signal and ground. You can discover the mode of each interface by examining the agency approval label on each port adapter, or by using the show controller cbus command.

Following is an example of discovering whether the PA-4E1G is in balanced or unbalanced mode:

Router# show controllers cbus Serial1/1/0, applique is G.703 Unbalanced [remainder of displayed text omitted from example] Serial1/1/1, applique is G.703 Unbalanced [remainder of displayed text omitted from example]

The PA-4E1G interface is divided into 32 time slots or frames. (See Figure 1-3.)

Interface Specifications

Time slot

H2402

Each of the 32 time slots is an 8-bit frame that transmits data at 64 kbps. Each of these time slots can be configured to carry data or to remain empty. (The P A-4E1G inserts an idle pattern i nto empty time slots.)

Time slot 0, or the first 8 bits, is reserved as overhead. The remaining 248 bits (31 frames with 8 bits each) are designated time slots 1 through 31. Time slot 16 is also designated as a framing slot when usi ng framed mode. When you use framed mode (G.704), you can configure time slot 16 to carry data and operate as any of the other slots; therefore, in framed mode time slot 0 must be designated as a framing signal; time slot 16 can be configured for either data or framing.

With framed mode (G.704) you can specify a bandwidth for the interface by designating 31 of the time slots for data and reserving time slot 0 for framing (timing). When you use framed mode, you must designate start and stop time slots; the slots within the start and stop boundaries are used for data, and the remaining slots are left idle. For example, on an interface with framing set on time slots 1 through 8, the interface carries data within the specif ied 8 frames, and frames 9 through 31 remain idle. Because each time slot transmits at 64 kbps, the interface operates at 512 kbps (8 frames x 64 kbps = 512 kbps).

By configuring 16 of the time slots to carry data and the other 16 to remain empty, you can essentially configure the interface for 1.024 Mbps (by leaving half the time slots empty and unable to carry data). The system inserts an idle pattern into unused time slots to identify them as overhead (unused for data). Only one contiguous time slot range can be used. In Private A utomatic Branch Exchange (PABX) systems, time slot 16 is always left unused. By default, time slot 16 is not enabled for data in the PA-4E1G interface. The command ts16 overrides the default and enables time slot 16 to carry data.

Unframed mode (G.703) uses all 32 time slots for data. None of the 32 time slots are used for framing signals. This allows each of the 32 time slots to transmit at 64 kbps; therefore, 32 time slots x 64 kbps =

2.048 Mbps. While unframed mode is the default, you can also specify unframed mode with the command timeslot 0-0, which specifies time slot 0 as the start slot with no stop (ending) time slot; therefore, all slots are used for data. The no timeslot command restores the default of unframed mode.

OL-3065-05

Framed mode supports a 4-bit cyclic redundancy check (CRC4), which you enable with a software command. The default is for no CRC.

Note The E1-G.703/G.704 interface on PA-4E1G is compliant with BABT 221.

For more information about CRC4 with a PA-4E1G on a VIP , Cisco 7100 series router, Cisco 7200 series router, or Cisco uBR7200 series router, refer to Chapter 4, “Configuring the PA-4E1G.”

LEDs

Chapter 1 Overview

The P A-4E1G has one row of three status LEDs for each port and one EN ABLED LED. (See Figure 1-4.) The green- and amber-colored LED for each port indicates port status.

Figure 1-4 PA-4E1G LEDs—Partial Front-Panel View

H9602

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

The following conditions must be met before the PA-4E1G is enabled:

• The PA-4E1G is correctly connected and receiving power.

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

• The system recognizes the PA-4E1G or a VIP with a PA-4E1G.

If any of the above con ditions are not met , or if the initializati on fails for oth er reasons, the enabled LED does not go on.

Table 1-1 lists port LED colors and indications.

Chapter 1 Overview

Note You must connect the correct type of interface cable for the port to operate.

Cables, Connectors, and Pinouts

The port adapter end of all E1-G.703/G.704 adapter cables is a DB-15 connector. At the network end, the adapter cable for unbalanced (75-ohm) connections uses a BNC connector. The adapter cables for balanced (120-ohm) connections u se DB-15, tw inaxial, or RJ-45 connections to accommodate connection standards in different countries.

Warning

It is a requirement of the statutory approval of the E1-G.703/G.704 interface that the jackscrews of the connector backshell are securely screwed down while the portadapter is operating.

Cables for balanced and unbalanced mode are available with the following types of network-end connectors:

• Unbalanced (75-ohm) coaxial cables with BNC connectors at the network end, which are used

primarily for connection in the United Kingdom. (See Figure 1-5.)
