Connect the T1/PRI Card for WAN Access
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
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.
You can connect the Cisco AS5300 to a T1 or E1/PRI card for WAN access. If you have a E1/PRI card, go to the next procedure.
You need four straight-through RJ-45-to-RJ-45 cables to connect the T1/PRI card to a WAN. These cables are not included.
Note To identify a straight-through cable, hold the connectors side-by-side, with the tab at the back. The wires are
in the same sequence at both ends of the cable.
Step 1
Connect one end of the straight-through RJ-45-to-RJ-45 cable to the T1 port labeled 0 on the rear panel of the
Cisco AS5300.
Connect the other end of the cable to the incoming T1 line (RJ-45 jack).
Step 2
Repeats Steps 1 and 2 to connect other cables to the remaining ports.
