Program BRI Trunks

Before You Begin

Ensure that:

• A BRI Network Services Unit and a Universal Network Services Unit are programmed

• Interconnect Restriction and Intercept Handling are programmed for each trunk.

• The local carrier service can support 64 Kbps data calls.

• Note: For video conferencing over a BRI interface, the central office (CO) must support 64 Kbps clear channel data calls.

Programming

To program BRI trunks:

1. Digital Link Descriptors form
   Enter "A" or "B" in the Address for Message Control field.
   Enter "DPNSS" in the Integrated Digital Access field.

2. Digital Links form
   Complete the Digital Link Descriptor Number field.

3. Class of Service Options form
   Set the ANI/DNIS ISDN Number Delivery Trunk field to "Yes".

4. MSDN-DPNSS-DASS II Trunk Circuit Descriptors form
   Enter "MSDN-DPNSS" in the Signaling Protocol field, "CEPT" in the Card Type field, "Incoming" or "Outgoing" (depending upon your system) in the Dual Seizure Priority field, "LT" for NA, or either "LT" or "NT" for EMEAAP in the BRI Mode field, and "Local Office" in the Far End Connection field.

   Assign a source connection to a Network Source Clock.

The system programming is now complete. The BRI NSU must now be programmed.

1. Connect a computer to the RS-232 port on the BRI NSU.

2. Log on to the BRI NSU.

3. Configure Usernames and Passwords.

4. Follow the Quick Setup instructions as required.

5. Complete specific programming for BRI.

6. Log off after all programming is complete.

7. Detach the computer from the port.
