How to Commission the Cisco AS5850 Universal Gateway Task 3. Configuring Channelized T1 or E1 This section shows how to configure channelized T1 or E1. You can allocate the available channels for channelized E1 and T1 in the following ways: • All channels can be configured to support ISDN PRI. • If you are not running ISDN PRI, all channels can be configured to support robbed-bit signaling (also known as channel-associated signaling). • All channels can be configured in a single channel group.
How to Commission the Cisco AS5850 Universal Gateway Tip To save the gateway configuration, save it to NVRAM. Verify To verify that your controller is up and running and no alarms have been reported: • Enter the show controller command and specify the controller type, slot, and port numbers: Gateway# show controller t1 1/7 T1 1/7 is up. No alarms detected. Framing is ESF, Line Code is B8ZS, Clock Source is Line Primary.
How to Commission the Cisco AS5850 Universal Gateway To configure channelized T3, perform the following steps. Step 1 Use the enable command and password to enter privileged EXEC mode. You are in privileged EXEC mode when the prompt changes to Gateway#. Gateway> enable Password: password Gateway# Step 2 Enter global configuration mode. You are in global configuration mode when the prompt changes to Gateway(config)#. Gateway# configure terminal Enter configuration commands, one per line. End with CNTL/Z.

How to Commission the Cisco AS5850 Universal Gateway Channelized T1 ISDN PRI offers 23 B channels and 1 D channel. Channelized E1 ISDN PRI offers 30 B channels and 1 D channel. Channel 24 is the D channel for T1, and channel 16 is the D channel for E1. ISDN provides out-of-band signaling using the D channel for signaling and the B channels for user data. Note • For more information on dial services, see the Dial Solutions Command Reference for your Cisco IOS software release.

This is a red alarm. The signal is recovered if the density of 1s reaches 12.5%. Recovery happens when four 1s are received within a 32-bit period. Remote Frame Alarm (RHEA) Indicates that an OOF framing pattern occurred at the remote end. This is a yellow alarm.
How to Commission the Cisco AS5850 Universal Gateway Task 6. Configuring the Serial Interfaces Configure the serial D channels to route incoming voice calls from the PSTN to the integrated modems. The behavior of the B channels is controlled by the D-channel configuration instructions. The D channel is the signaling channel. Table 7 describes the relationship between T1 controllers and serial interfaces.
