	Incoming Line/Trunk Type	3

Use the procedure in this section to match incoming trunks to the continuous sequence of line/trunk jacks on the control unit, beginning with the first line/trunk jack (logical ID 1).

NOTE:

(Key mode only) If the system is registered with the FCC registration number of AS59CM-7914-KF-E, and the processor module has been modified for Permanent Key mode, you can connect loop-start trunks to the GS/LS type line/trunk jacks. With the KF registration number, ground-start trunks are allowed only when the system includes DS1 connectivity dedicated as a T1 type and the channels are used to emulate ground-start trunks.

This procedure also includes instructions for assigning a label to identify the line/trunk being used.

Planning Form Instructions

1.In the Incoming Line/Trunk Type column of Form 2c, write the type of line/trunk you plan to connect to each line/trunk jack, T1 channel or BRI channel: Main No., personal line, FX (Foreign Exchange), WATS (include band), DID, or Tie. (Contact the local telephone company for line/trunk information.) Use the following guidelines:

■Group trunks together according to type: basic loop-start or ground-start trunks, and special-purpose loop-start or ground-start trunks. (DID, PRI, T1, BRI and tie trunks are automatically grouped according to type since they require specific types of modules.) The local telephone company supplies the information you need to identify the specific trunks connected to each line/trunk jack on each DID and tie trunk module and each channel on each 100D or 800 NI-BRI module.

■Use line/trunk jacks at the beginning of the sequence for basic ground-start and/or basic loop-start trunks. Use jacks later in the sequence for special-purpose trunks such as WATS or FX.

■If a line/trunk such as WATS is only inbound or only outbound (not two-way), include that information along with the line/trunk type.
