How Drop and Insert works

Access Server Administrators’ Reference Guide 

Figure 58. Drop and insert diagram

This functionality can only be done on robbed bit lines. You can not per-
form drop and insert on a PRI line.

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. 

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.
