Jacks for Outside Lines
3-4
Line Connections
Identify the specific outside lines you want to connect to each loop-start and
ground-start/loop-start line jack. Connect outside lines to a continuous
sequence of line jacks on the control unit, beginning with the first line jack
(logical ID 1). Use line jacks at the beginning of the sequence for basic loop-
start lines. Use jacks later in the sequence for special-purpose lines such as
WATS or FX (foreign exchange).
Group lines together according to type: basic loop-start lines or special-purpose
loop-start lines. PRI, T1, and tie trunks are automatically grouped according to
type since they require specific types of modules. Your local telephone
company supplies the information you need to identify the specific lines
connected to each line jack on each tie-trunk module and each channel on each
100D module.
Note: If the system is registered with the FCC registration number of AS59CM-
7914-KF-E, only loop-start lines can be connected to the GS/LS type line jacks.
With the KF registration number, ground-start lines are allowed only when the
system includes a DS1 facility dedicated as a T1 type and the channels are
used to emulate ground-start lines.
Planning Form Instructions
1 . On Form 2c, under "Line Type", write the type of line or tie trunk you plan
to connect to each line jack or T1 channel—basic, FX, WATS (include
band), tie, (refer to the local telephone company line information list).
If a line such as WATS is only inbound or outbound (not two way),
include that information along with the line type.
If the lack type shown in the "Jack Type" column is GS/LS, next to the
line type (basic, FX, or WATS), write either "GS" or "LS' to indicate the
line type. For a T1 line not used at this time, write "unequipped".
Note: For other T1 or PRI lines, the kind of service connected (such as
Megacom 800) will be completed later.
2. In the "Telephone Number or Equipment" column, write the telephone
number for each outside line on the line with the logical ID for its line jack.
If you don't yet know the telephone number, leave the column blank and
enter the information later.
Note: Be sure the line type associated with each telephone number
matches the jack type.
