How Drop and Insert works
Figure 59. Drop and insert diagram
Note
This functionality can only be done on robbed bit lines. You can not
perform 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 exten-
sion on the PBX.
