Safety with Electricity

Warning   Read the installation instructions before you connect the system to its power source.

Warning   Ultimate disposal of this product should be handled according to all national laws and regulations.

Warning   Only trained and qualified personnel should be allowed to install or replace this equipment.

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

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

Warning   Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.

Warning   The ISDN connection is regarded as a source of voltage that should be inaccessible to user contact. Do not attempt to tamper with or open any public telephone operator (PTO)-provided equipment or connection hardware. Any hardwired connection (other than by a nonremovable, connect-one-time-only plug) must be made only by PTO staff or suitably trained engineers.

Warning   To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

Warning   Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.

Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to safely channel unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal part of the chassis.


Caution   For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm).

Software Requirements

The Cisco AS5300 quad T1/PRI or E1/PRI feature cards require Cisco IOS Release 11.2(9)P or higher.

Required Tools and Equipment for Installation

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

Cisco AS5300 access server

Feature card removal tool (included)

Medium-size flat-blade screwdriver (1/4 inch [0.625 cm])

ESD-preventive wrist strap and mat

Antistatic bag (optional)


Caution   The feature cards are not hot-swappable (that is, you cannot remove or install 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.

Quad T1/PRI Card Overview

The quad T1/PRI card (see Figure 1) includes four RJ-45 ports. Cables are not included with the cards; however, cable specifications and port pinouts are listed in the section "Quad T1 PRI Card Port Pinouts," page 26.

A 10-position rotary switch allows the user to choose which of the four ports is selected for monitoring through the two sets of bantam jacks (TXMON, TXIN, TXOUT, and RXMON, RXIN, RXOUT). See "Using the Bantam Jacks," page 26 for a detailed description of the signals available at each of the bantam jacks. The LED labeled MON at each port lights to indicate that the port is selected for monitoring. Only one port can be selected at a time. None of the ports is selected when the switch is set to the Off position.

Figure 3 Receive Shield Jumpers for 75-ohm Unbalanced Ports

Removing a Feature Card

To remove a feature card, refer to and take these steps:


Step 1 Turn the power switch on the access server OFF and disconnect site power.

Warning   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.

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.

Step 2 Attach an ESD-preventive wrist strap.

Step 3 Remove all interface cables from the rear panel of the access server.

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

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

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.

Figure 4 Removing a Feature Card (Carrier Card Shown)

Step 5 Insert the feature card removal tool so that the slots in each arm of the tool are behind the shoulder of each captive screw, as shown in , and carefully pull the removal tool toward you until the feature card slides free of the chassis.

.


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

Figure 5 Using the Feature Card Removal Tool

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

Installing a Feature Card

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


Step 1 Attach an ESD-preventive wrist strap.

Step 2 Remove the new feature card from the ESD-preventive shipping material.

Step 3 Slide the card into the slot until it touches the backplane connector.

Step 4 Align the captive screws with their holes, and then seat the card completely.

Step 5 Tighten the two captive screws to secure the card to the chassis.

Step 6 If the access server 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.

Configuring Software

After you install or replace the feature card, configure the software as described in the following sections.

How to Find Command Options

Configures e&m-fgb signaling to support modem pooling and the digital number identification service (DNIS) over channelized T1 lines.

You must specify the tone type: mf or dtmf.

By configuring DNIS as part of the cas-group command, the system collects DNIS digits for incoming calls, which are redirected to specific modem pools. You must be running Mica modems in the system and have at least 10% of your total modems in the default modem pool. Free modems are needed in the default pool to detect the incoming called number or DNIS before handing the call off to the appropriate modem pool. Therefore, a second modem is needed to handle each incoming call.

Note: Make sure your switch provides inband address information for incoming analog calls before you enable this feature.

Table 9 Debug Dialer Messages 

Message
Description

PRI0: No dialer string defined. Dialing cannot occur

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. Re-enter the dialer-group command in step 6 in the "Configure" section.

PRI0: Attempting to dial xxxxxxxxxx

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

Displayed if the phone call could not be placed. This can be due to a lack of memory, full output queues, or other problems.

PRI0: disconnecting call

Displayed when the Cisco AS5300 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. When you finish viewing the messages, enter no debug isdn q931 to turn off the messages. See for explanations of the error messages.

Table 10 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-T11 -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 it is associated with. 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 Recommendation 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.

Using the Bantam Jacks

If a T1 controller does not come up, or there is a large number of errors associated with a particular controller, you might be able to determine whether the problem is in the quad T1/PRI card or in an external T1 line by using the bantam jacks. A rotary switch at the front of the T1/PRI card selects which of the four T1 lines are to be monitored/inspected. The LED labeled MON indicates which T1 line is connected to the bantam jacks.

External test equipment, such as a bit error rate tester, can be used to inject data into the TX IN jack and receive data from the RX OUT jack with the remote location in loop back. This would be an invasive test that would disrupt connections on that T1 port. Another example is to use passive monitoring equipment that can listen on the TX MON and RX MON jacks during regular operation to detect T1 errors.

Connecting test equipment to the following Bantam jacks provides various functions:

TX MON can monitor signals coming out of the RJ-45 port without interrupting normal data transmission.

RX MON can monitor signals going in to the RJ-45 port without interrupting normal data transmission.

TX IN will break the normal data transmission and a test signal is injected into the Bantam jack and out the RJ-45 port. The quad T1/PRI card is isolated from the test.

RX IN will break the normal data transmission and inject a test signal into the quad T1/PRI card through the Bantam jack. The RJ-45 port and its PRI lines connection will be disconnected from the quad T1/PRI card.

TX OUT will break the normal data transmission and divert the output of the quad T1/PRI card to the Bantam jack. The RJ-45 port and its external connections will be disconnected from the quad T1/PRI card.

RX OUT will break the normal data transmission. The quad T1/PRI card circuits will be disconnected from the external PRI connection. The Bantam jack is connected to the RJ-45 port RX pins.

Quad T1 PRI Card Port Pinouts

lists the quad T1 PRI card port pinouts. Use a straight-through RJ-45-to-RJ-45 cable to connect the T1 port to an RJ-45 jack.
