3. For systems that include a 100D module, do one of the following in the
Jack Type column:
You are now ready to match incoming trunks to these available jacks as described
in the next section.
Incoming Line/Trunk Type
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: NOTE: 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.

If the module will emulate trunks or will be used for digital data
transmission, write the appropriate jack type code (see Table 3 2)
for the channels being used (for example, T1-LS, T1-TIE, or T1-S56),
or write T1 if the channels are not being used at this time.
If the module will connect services (for example, Megacom,
Megacom 800, and so on), write PRI for all 24 logical IDs of PRI-
type modules.
