Installing Dual T1/PRI or E1/PRI Feature Cards in Cisco AS5200 Universal Access Servers

The Cisco AS5200 dual T1/PRI or E1/PRI feature cards require Cisco IOS Release 11.2(7)P or higher.

Required Tools and Equipment

To install the dual T1/PRI or E1/PRI feature cards, you will also need the following tools and equipment (some of which are not included):

Feature Cards

The Cisco AS5200 includes three slots in which you can install feature cards. You can install one of the following feature cards in any of the three available slots:

The feature cards are not hot-swappable (that is, you cannot install or remove them when the power to the access server is ON). Be sure to turn OFF the power to the access server before installing or removing feature cards. Failure to do so can damage the access server.

Dual T1/PRI Card

The dual T1/PRI card (see Figure 1) routes incoming digital T1 lines to the 6-port or 12-port modules. The dual T1/PRI card provides RJ-48C connectors to terminate trunks. The dual T1/PRI card performs all necessary equalization and gain functions to support 6000 feet of 24-gauge unshielded cable. This card complies with all Bell Core standards relating to T1 (ANSI T1.403) alarms, loopbacks, and error detection. The dual T1/PRI card is equipped with integrated CSUs.

The dual T1/PRI card handles up to 48 digital signal level 0 (DS-0) channels from two trunks. Each channel carries either a pulse code modulation (PCM)-encoded voice channel or digital data. The dual T1/PRI card supports 64-kbps clear channel operation for data or voice channels and feature group B operation for voice channels.

Figure 1 Dual T1/PRI Card

Table 1 describes a typical maximum configuration. Note that the dual E1/PRI and the carrier cards are not slot dependent. Even though the system can contain 60 ports, the dual E1/PRI card can only support 48 simultaneous calls. The 12 extra ports are used for redundancy.

Table 1 Cisco AS5200 T1/PRI Port Configurations

Slot	Card	Maximum Ports
2	6-port MICA modem module carrier card or 12-port Microcom/V.110 carrier card	30 MICA modem ports or 24 Microcom/V.110 modem ports
1	6-port MICA modem module carrier card or 12-port Microcom/V.110 carrier card	30 MICA modem ports or 24 Microcom/V.110 modem ports

Indicators

Table 2 describes the LEDs on the dual T1/PRI feature card. The LEDs indicate the current operating condition of the card. You can observe the LEDs, note any fault condition that the card is encountering, and contact your system administrator or a customer service representative if necessary. Refer to the sections "Cisco Connection Online," and "CD-ROM/WWW Feedback," for more information.

Table 2 Dual T1/PRI Feature Card LEDs

LED	State	Description
Board Activity	Flickering	The CSU/DSU in the card is communicating with a remote CSU/DSU.
Board OK	On	The T1/PRI card has passed initial power-ON diagnostics tests and is operating normally.
Loopback	On	A local or remote loopback diagnostic test is running on the associated T1 port.
Remote alarm	On	A remote alarm indication signal (AIS) has been received on the associated T1 port. The AIS is received when there has been a loss of signal (LOS).
Local alarm	On	The associated T1 port has detected local loss of signal (LOS) or out of frame (OOF) errors.

You can isolate problems on the dual T1/PRI card by connecting external test equipment to the RECEIVE jack to monitor signals coming into the RJ-48C port without interrupting normal data transmission. You can use the TRANSMIT jack to inject data, which interrupts normal data transmission.

Dual E1/PRI Card

The dual E1/PRI card (see Figure 2) is installed in the Cisco AS5200 to provide physical termination for two E1/PRI lines. The card is designed to support the E1 cable standard of 30 Bearer (B) channels for voice and data, one Data (D) channel for signaling, and one channel for framing. Each channel transmits at up to 64 kbps for a combined total of 2.048 Mbps for each E1/PRI line.

The Cisco AS5200 is used to service calls from users accessing remote services using a variety of network protocols. Calls are terminated in the Cisco AS5200 through up to 60 modems or modem/terminal adapter combinations. Your access server can support a combination of MICA modems, Microcom modems, and V.110 terminal adapters. User data can then be routed through the Ethernet or synchronous serial ports on the Cisco AS5200 chassis.

Figure 2 Dual E1/PRI Card

Table 5 describes a typical maximum configuration. Note that the dual E1/PRI and the carrier cards are not slot dependent. Even though the system can contain 72 ports, the dual E1/PRI card can only support 60 simultaneous calls. The 12 extra ports are used for redundancy.

Table 5 Cisco AS5200 E1/PRI Port Configurations

Slot	Card	Maximum Ports
2	6-port MICA modem module carrier card or 12-port Microcom/V.110 carrier card	30 MICA modem ports or 24 Microcom/V.110 modem ports

Two DB-15 connectors for physically terminating two E1/PRI lines.
Channelized E1 support for assigning E1 time slots in 1 to 30 channel groups.
Optional 12 modem ports (Microcom) or terminal adapters for call termination on E1 channels. The optional 12 modems and two carrier cards with 48 modems are required if a modem is needed for each of the 60 B channels contained in two E1/PRI lines.
Optional 30 modem ports (MICA) for call termination on E1 channels.
LEDs to indicate the operating condition of the E1/PRI lines.
Full management of the dual E1/PRI card though a command line interface or CiscoWorks network management software.

The dual E1/PRI card includes two DB-15 ports for terminating 120-ohm balanced lines or 75-ohm unbalanced lines. Jumper settings on the card configure the ports for the line termination. Jumper positions and settings are listed in the section "Setting E1 Port Jumpers,".

The E1 interface card may only be installed in an ACA-permitted customer equipment or a data terminal equipment that is exempted from ACA's cabinet which has screw-down lids to stop user access to overvoltages on the customer equipment. The customer equipment has circuitry that may have telecommunications network voltages on them.

Incorrect connection of this or connected equipment to a general purpose outlet could result in a hazardous situation.

This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.

The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.

Installing a Feature Card

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

For DC-powered units only, note the following warning:

Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

To install a new feature card, refer to Figure 7 and take these steps:

Step 1 Remove the feature card from the ESD-preventive shipping material.

Step 2 Slide the card into the slot until it touches the backplane connector.

Note If you have a dual E1/PRI card, change the jumper settings before installing the card. Refer to the section, "Setting E1 Port Jumpers," page 14 for more information.

Figure 7 Installing a Feature Card (Carrier Card Shown)

Step 3 Align the captive screws with their holes, and then seat the card completely.

Step 4 Tighten the two captive screws on the feature card to secure it to the chassis.

Step 5 If the Cisco AS5200 is configured with fewer than three cards, make sure that a blank slot cover is installed over each open slot to ensure proper airflow inside the chassis.

Removing a Feature Card

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.

Do not work on the system or connect or disconnect cables during periods of lightning activity.

For DC-powered units only, note the following warning:

Note To remove a feature card, refer to Figure 8 and Figure 9 and take these steps:

Step 1 Attach an ESD-preventive wrist strap.

Step 2 Turn the power switch on the Cisco AS5200 OFF and disconnect site power.

Step 3 Remove all interface cables from the rear panel of the Cisco AS5200.

Step 4 Loosen the two captive screws that secure the feature card or blank slot cover to the chassis until each screw is free of the chassis.

Step 5 Hold the captive screws and gently pull the feature card free of the chassis.

Step 6 Set the removed feature card aside on an ESD-preventive mat.

The EMI protective devices on the feature cards are designed to make the cards fit tightly. When removing the cards, they might release suddenly. Exercise caution when removing cards.

Step 7 If the feature card is hard to remove:

For the Dual T1/PRI board, insert a flat-top screwdriver vertically into the prying slot of the board and gently pry the board loose. (See Figure 8.) Then, hold the captive screws and gently pull out the card until it slides free of the chassis.
For the Dual E1/PRI board, insert a flat-top screwdriver vertically into the center of the feature board and gently pry the board loose. (See Figure 9.) Then, hold the captive screws and gently pull out the card until it slides free of the chassis.

Configuring the Dual T1/PRI and E1/PRI Feature Cards

This section describes how to use the Cisco IOS software command line interface to configure basic Cisco AS5200 functionality. Basic Cisco AS5200 functionality includes LAN and WAN configuration (including ISDN PRI and channelized T1 and E1). Follow the procedures in this section to configure the Cisco AS5200 after installing a new T1/PRI or E1/PRI feature card.

This section does not describe every configuration possible—only a small portion of the most commonly used configuration procedures. For more advanced configuration topics, refer to the Cisco IOS configuration guide and command reference publications. These publications are available on the Documentation CD-ROM that came with your Cisco AS5200, on the World Wide Web from Cisco Connection Online (CCO), or you can order printed copies separately. Refer to the sections "Cisco Connection Online," and "CD-ROM/WWW Feedback," for more information.

For information about features supported by the Cisco IOS release installed on your Cisco AS5200, see the release notes that shipped with your chassis.

Prerequisites for Configuring the Cisco AS5200

Before you begin, make sure you have completed the following tasks:

Connect a console to the Cisco AS5200 and turn on the server. If you need instructions on how to connect a terminal console to the server, refer to the Cisco AS5200 hardware installation guide.
Write down the IP address of your Ethernet (LAN) interface.
Write down the set of available IP addresses to be assigned to dial-in IP clients.
Make sure your Cisco AS5200 is connected to the Ethernet network and the T1 PRI line. For more information about connecting cables, refer to the quick reference cards and the Cisco AS5200 Universal Access Server Hardware Installation Guide, which shipped with your Cisco AS5200.
Write down the ISDN switch type, framing type, and line code of your T1 PRI or E1 PRI line. Obtain this information from your telephone company service provider.

Note If you do not type anything for 10 minutes while you are configuring your system, the session times out and is disconnected. If it times out, the message "Press RETURN to get started" appears. This is not an error. If this message appears, press Return and the Router> prompt appears again.

How to Find Command Options

This section explains how to display options for a command. To display options for a command, enter a ? at the configuration prompt, or after entering part of a command followed by a space. The configuration parser displays options available with the command. For example, if you were in global configuration mode and wanted to see all the keywords and arguments for the command arap, you would type arap ?.

Table 10 shows examples of this function:

The second half of the messages display information for Serial 1:23. Ignore those messages.

Tips

If you are having trouble, check the following:

Make sure the cable connection is not loose or disconnected if the Layer 1 Status is "Deactivated." This status message indicates a problem at the physical layer.
There might be a problem with your telco, or the framing and line code types you entered might not match your telco's. A Layer 2 error indicates that the Cisco AS5200 cannot communicate with the telco. There is a problem at the data link layer.

Verifying Channelized T1 or E1

To verify your controller is up and running and is not reporting errors, enter the show controller t1 or show controller e1 command and specify the port number.

 
5200# show controller t1 0

 
T1 0 is up.

 
  No alarms detected.

 
  Version info of slot 0:  HW: 2, Firmware: 16, PLD Rev: 2

Note the following:

The controller must report being up.
No errors should be reported.

Tips

If you are having trouble, check to make sure the show controller t1 or show controller e1 output is not reporting alarms or violations.

Configuring the D Channels for Modem Signaling

For each ISDN PRI line, configure the ISDN D channels, which carry the control and signaling information for ISDN calls. Use the commands from Table 13 to configure the ISDN D channels.

Table 13 Configuring the D Channels for Modem Signaling

Step	Command	Purpose
1	5200> enable Password: <password> 5200#	Enter enable mode. Enter the password. You have entered enable mode when the prompt changes to 5200#.
2	5200# config term Enter configuration commands, one per line. End with CNTL/Z. 5200(config)#	Enter global configuration mode. You have entered global configuration mode when the prompt changes to 5200(config)#.
3	5200(config)# interface serial [0:15 \| 0:23] 5200(config-if)#	Enter serial interface configuration mode. After you have configured the controller, a corresponding D channel serial interface is created instantly. For example, serial interface 0:23 is the D channel for controller 0. You must configure each serial interface to receive incoming and send outgoing modem signaling.
4	5200(config-if)# ip address 172.16.253.254 255.255.255.0	Assign an IP address and subnet mask to the interface.
5	5200(config-if)# isdn incoming-voice modem	Configure all incoming voice calls to go to the modems.
6	5200(config-if)# dialer-group 1	Assign the serial interface to dialer group 1. The dialer group number is used with the dialer-list command to determine which packets will be "interesting" and activate the ISDN connection. Interesting packets meet the criteria specified by the dialer-list command.
7	5200(config-if)# encapsulation ppp	Change the default to encapsulation PPP so you can enter PPP commands.
8	5200(config-if)# ppp multilink	Enable PPP multilink on the serial interface.
9	5200(config-if)# ppp authentication chap pap	Enable CHAP and PAP authentication on the serial interface.
10	5200(config-if)# peer default ip address pool default	Support dial-in PC clients.
11	5200(config-if)# end 5200# %SYS-5-CONFIG_I: Configured from console by console 5200#	Return to privileged EXEC mode. This message is normal and does not indicate an error.

Verifying the D-Channel Configuration

Enter the no debug dialer command to turn off the messages. If you do not turn off the messages, they will continue to display. See Table 14 for descriptions of the debug dialer messages.

Table 14 Debug Dialer Messages

Message	Description
PRI0: No dialer string defined. Dialing cannot occur.	This message is displayed when a packet is received that should cause a call to be placed. However, there is no dialer string configured, so dialing cannot occur. This message usually indicates a configuration problem. Reenter the dialer string command in the configuration.
PRI0: Attempting to dial xxxxxxxxxx	This message indicates that a packet has been received that passes the dial-on-demand access lists. That packet causes dialing of a phone number. The xxxxxxxxxx variable is the number being called.
PRI0: Unable to dial xxxxxxxxxx	This message is displayed if for some reason the phone call could not be placed. This might be due to a lack of memory, full output queues, or other problems.
PRI0: disconnecting call	This message is displayed when the Cisco AS5200 attempts to hang up a call.
PRI0: idle timeout PRI0: re-enable timeout PRI0: wait for carrier timeout	One of these three messages is displayed when their corresponding dialer timer expires. They are mostly informational, but are useful when debugging a disconnected call or call failure.

If dialing cannot occur, check the configuration by entering the debug isdn q931 command:

 
5200# debug isdn q931

 
%LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0:22, changed

ISDN PRI 3: entering process_rxstate, CALL_CLEARED

 
ISDN PRI 3: received message 1F

 
ISDN Event: Hangup call to call id 0xCE2 on dsl 2

Enter the no debug isdn q931 command to turn off the messages. If you do not turn off the messages, they will continue to display. See Table 15 for descriptions of the debug messages.

Table 15 Debug ISDN Messages

Message	Description
TX ->	Indicates this message is being transmitted from the local router (user side) to the network side of the ISDN interface.
RX <-	Indicates this message is being received by the user side of the ISDN interface from the network side.
SETUP	Indicates the SETUP message has been sent to initiate call establishment between peer network layers. The message can be sent from the local router or network.
pd	Indicates the protocol discriminator. The protocol discriminator distinguishes messages for call control over the user-network ISDN interface from other ITU-T1-defined messages, including other Q.931 messages. The protocol discriminator is 8 for call control messages such as SETUP.
callref	Indicates the call reference number in hexadecimal. The field value indicates the number of calls made from the router (outgoing calls) or the network (incoming calls). Note that the originator of the SETUP message sets the high-order bit of the call reference number to 0. The destination of the connection sets the high-order bit to 1 in subsequent call control messages, such as the CONNECT message. For example, callref = 0x04 in the request becomes callref = 0x84 in the response.
Bearer Capability	Indicates the requested bearer service to be provided by the network.
i=	Indicates the Information Element Identifier. The value depends on the field with which it is associated. Refer to the ITU-T Q.931 specification for details about the possible values associated with each field for which this identifier is relevant.
Channel ID	Indicates the Channel Identifier. The value 83 indicates any channel, 89 indicates the B1 channel, and 8A indicates the B2 channel. For more information about the Channel Identifier refer to ITU-T Q.931.
Called Party Number	Identifies the called party. This field is only present in outgoing SETUP messages. It can be replaced by the Keypad facility field. This field uses the IA5 character set.
RELEASE	Indicates that the sending equipment will release the channel and call reference. The recipient of this message should prepare to release the call reference and channel.
RELEASE_COMP	Indicates that the sending equipment has received a RELEASE message and has now released the call reference and channel.
