LD 117 – Define the zone digit manipulation for the branch office zone at the main office.

Command

Description

CHG ZDP <zone> <DialingCode1> <DialingCode2> <DialingCode3>

Define the dialing plan for the branch office zone, where DialingCode1, DialingCode2, and DialingCode3 are inserted into the dialed digits between the Access Code and the remainder of the dialed number.

The ZDP and ZACB (step 1 on page 175) properties are used to configure the digit manipulation behavior of the branch office zone.

The ZDP property is inserted between the Access Code specified in the ZACB command and the dialed digits. This zone-based digit manipulation allows the main office Call Server and the network NRS to distinguish the SRG users’ calls from the main office users’ calls, and route them accordingly. The digit manipulation occurs before any digit processing in the main office Call Server or NRS.

Note: If DialingCode1, DialingCode2, or DialingCode3 are already present in the dialed digits, then they will not be re-inserted.

Nortel recommends that the ZDP attribute for each branch office zone be set to a unique non-dialable number within the dialing plan (for example “1019” or “999”). This unique non-dialable number can then be used, when configuring the main office ESN Special Number (step 4 of Procedure 11 on page 181) and the NRS

(H.323 Gatekeeper) (Procedure 12 on page 184), to route the calls to the branch office for connection to the local PSTN.

For example, assume AC1 = 1, AC2 = 2, ZACB = AC1 AC1, and

ZDP = 101.

If an branch office user dials “1 87654321”, zone digit manipulation occurs because AC1 was dialed and ZACB = AC1 AC1. ZDP is inserted in the dialed digits to form a digit string of “1 101 87654321”. The call is routed differently than with the digits “1 87654321”. ESN configuration at the main office Call Server (step 4 on page 181)
