3.3 CHANGES TO CENTRAL OFFICE TRUNKING
Public Exchange (PE) changes may be needed to
- Add trunking capability.
- Change the order of trunk hunting.
- Create new trunk hunting groups.
- Add, change, or delete 800 services.

- Split the hunt group (directory listed number), allowing some trunks to be directed to the console and
some to Octel Overture 200/300.
Additional Trunking
The specific number of PBX lines and trunks depends on the number of ports and the desired trunking
arrangement.
Although the Octel Overture 200/300 port drops off after it transfers a call, the PE trunk is still occupied
during the entire call. When you decide how many trunks to direct to the Octel Overture 200/300,
remember each trunk is occupied from the time the call is placed until the caller hangs up. As a result,
the Octel Overture 200/300 can answer incoming calls from more trunks than it has ports.
Determine how many trunks to direct to the Octel Overture 200/300 by using PBX traffic data and the
traffic engineering tables. The tables are designed to help decide how to use the Octel Overture 200/300
most effectively for a given situation. After collecting the traffic data, it may be necessary to order
changes from the telephone company to add or alter the number of trunks.
Splitting Trunk Groups
If one two-way trunk group will be separated into two or more groups, the rotary hunting of the trunks
must be changed.
The Octel Overture 200/300 handles only incoming calls. If the trunks that the Octel Overture 200/300
answers are two-way trunks (also used for outgoing calls), make sure that sufficient trunks are available for
both incoming and outgoing calls. Additional trunks or changes to the type of trunks may be advisable. For
information on Direct Access Cards, refer to the Direct Access Card (DAC) Reference Manual.
DID Trunks: Using the DID/E&M Trunk Interface
The DID/E&M Trunk Interface monitors and intercepts DID/E&M calls. These trunks do not get
directed, via the DIL feature, to the Octel Overture 200/300 hunt group.
DID/E&M trunks using the DID/E&M Trunk Interface must be rewired to route through the DID/E&M
Trunk Interface module. Coordinate the installation with PE personnel to prevent the PE from busying out
the trunks. No changes are necessary to the DID trunk equipment or DID programming in the PBX. Refer
to the DID/E&M Trunk Interface Installation and Maintenance manual for more detailed information.
