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.
