T1 or PRI Lines and “Trunk-Side” Service

The x2 server requires a trunk interface -- a T1 (channelized or PRI) or E1 (R2 or PRI)

trunk connected directly to the chassis (or a BRI line connected to an I-modem). In a

trunk-side configuration, once the user’s analog call is converted to digital and sent

over digital trunks through the carrier network, the call stays digital until it reaches the

Total Control chassis through a T1 or PRI trunk.

A Trunk-Side Configuration.

A line-side configuration is not suitable for x2 because the call undergoes more than one

analog-digital conversion. An example of line-side service: some central offices (COs)

implement channel banks that break T1 signals down, carry the signals over two-wire

connections and bring those connections back into another T1 through a second channel

bank. Line-side service might be used in a CO where there is older equipment. Line-side

service also causes a phenomenon called “near-end echo,” which introduces

impairments.

Troubleshooting Calls (x2 Client)

Troubleshooting Courier Calls

Follow the steps very methodically. Silly oversights have been made by the best of us!

Checklist (Details for each item are below and in Appendix A.)

1. Examine the Courier status messages.

2. Verify that the host is x2-capable.

3. Ensure that the modem has proper x2 software and that it’s enabled.

4. Ensure that the S-registers are set properly.

5. Ensure that the analog line is capable of x2.

6. Disconnect any other devices that share the analog line.
