| 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:
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). |
The Cisco AS5300 quad T1/PRI or E1/PRI feature cards require Cisco IOS Release 11.2(9)P or higher.
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):
| 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. |
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,".
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," 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.
Table 1 lists the network specifications you should consider before connecting the quad T1/PRI card to a network, and Table 2 explains the card LEDs.
| Description | Specification |
|---|---|
Line rate | 1.544 Mbps |
Data rates | Number x 56 or number x 64 kbps, where number = 1 to 24 |
Standards | AT&T Pub. 62411, 54016, and 43801 |
| LED | State | Description |
|---|---|---|
Activity (ACT) | Flickering | The CSU/DSU in the card is communicating with a remote CSU/DSU. |
Board OK (OK) | On | The T1/PRI card has passed initial powerup diagnostics tests and is operating normally. |
Loopback (LB) | On | Local and remote loopback is activated on the associated T1 port. |
Monitor (MON) | On | Using the MON SEL switch, the signals to/from the associated T1 port have been switched to the bantam jacks for test purposes. Only one port can be selected for monitoring. Normally, none of the MON LEDs should be on. |
Remote Alarm (RA) | On | An alarm has been received on the associated T1 port, indicating loss of signal (LOS) or loss of multiframe alignment (OOF) at the remote node. |
Local Alarm (LA) | On | The associated T1 port has detected loss of signal (LOS) or loss of multiframe alignment (OOF) errors on the local node. |
The quad E1/PRI WAN card includes four RJ-45 ports for terminating 120-ohm balanced lines or 75-ohm unbalanced lines. Cables are not included with the card; however, cable specifications and port pinouts are listed in the section "Quad T1 PRI Card Port Pinouts," and in the section "Quad E1 PRI Card Cable Assemblies and Pinouts,".
| Warning 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. |
| Warning Incorrect connection of this or connected equipment to a general purpose outlet could result in a hazardous situation. |
| Warning 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. |
| Warning The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. |
Table 3 explains the card LEDs.
A 10-position rotary switch (labeled IMP SEL, see Figure 2) allows you to choose the number of ports that are terminated as 75-ohm unbalanced lines. The LED labeled 120 at each port indicates the input impedance of that port. If the LED is on, it indicates the impedance of the port is set to 120 ohms. If the LED is off, it indicates the impedance of the port is set to 75 ohms.
The input impedance of each port for various impedance selection switch settings is shown in Table 4.
| Switch Position | Port 0 | Port 1 | Port 2 | Port 3 |
|---|---|---|---|---|
1 | 75 ohm | 120 ohm | 120 ohm | 120 ohm |
2 | 75 ohm | 75 ohm | 120 ohm | 120 ohm |
3 | 75 ohm | 75 ohm | 75 ohm | 120 ohm |
4 | 75 ohm | 75 ohm | 75 ohm | 75 ohm |
120 ohm | 120 ohm | 120 ohm | 120 ohm |
Jumpers on the quad E1/PRI card configure the 75-ohm unbalanced ports so the receive shield is connected to ground. You can remove these jumpers to disconnect the receive shield from ground (see Figure 3Quad E1/PRI Card LEDs).
To remove a feature card, refer to Figure 4 and take these steps:
| 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.
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 Figure 5, 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. |
Step 6 Set the removed feature card aside on an ESD-preventive mat.
To install a new feature card, refer to Figure 4 and take these steps:
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.
After you install or replace the feature card, configure the software as described in the following sections.
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, typed the command arap, and wanted to see all the keywords and arguments for that command, you would type arap ?.
Table 5 shows examples of this function:
| Command | Comment |
|---|---|
| Enters enable mode. Enters the password. You have entered enable mode when the prompt changes to |
| Enters global configuration mode and the prompt changes to |
| Specifies the T1 controller that you want to configure using the controller T1 number global configuration command |

| Displays the only command (timeslots) available in cas-group 1. |
| Displays the range for the timeslot option. Specifies a timeslot range of values from 1 to 24. You can specify timeslot ranges (for example, 1-24), individual timeslots separated by commas (for example 1, 3, 5), or a combination of the two (for example 1-3, 8, 17-24). The 16th time slot is not specified in the command line, because it is reserved for transmitting the channel signaling. |
| Displays the two commands (service and type) available for the timeslots. |
| Lists supported signaling types. |
| Displays the types of channel-associated signaling available for the e&m-fgb type. |
| Displays the options supported for the DTMF tone signaling option. |

PRI0: Dialing cause: PRI0: ip PERMIT
| Message | Description |
|---|---|
| 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. |
| 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. |
| Displayed if the phone call could not be placed. This can be due to a lack of memory, full output queues, or other problems. |
| Displayed when the Cisco AS5300 attempts to hang up a call. |
| 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 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:
Table 13 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.
