How Drop and Insert works 141

Access Server Administrators’ Reference Guide 10 • Drop and Insert

Figure 58. Drop and insert diagram

Note

This functionality can only be done on robbed bit lines. You can not per-

form drop and insert on a PRI line.

Using Drop and Insert

1. Configure each WAN port doing drop and insert. Links 1 and 2 perform drop and insert together. Links 3

and 4 perform drop and insert together.

The line type/coding for all of the lines can be either D4/AMI or ESF/B8ZS

WAN A can have the following types of line signalling:

– EMWinkStart

– GroundStart

– LoopStart

– EMImmediate

WAN B and x on PBX must be configured identically.

WAN B can have the following types of line signalling:

– EMWinkStart

– EMImmediateStart

2. Set the Desired Function for each channel on WAN A and B to dropInsert(7) (using channel assignment

under the T1/E1 link that is going to be performing drop and insert). The channels on WAN A selected

for drop and insert must match the channels on WAN B selected for drop and insert.

Note

We do not send digits with the EMWinkStart signalling. What this means is

that you can not direct the inbound call to a specific extension on the PBX.
