XE, Generic 1, Generic 2 (universal module), and Generic 3, locate the TN circuit packs shown below. For
System 85 and Generic 2 (traditional module), locate the SN packs:
• TN754 or SN270B connected to MTDM-1 ____________________ (equipment location)
• TN754 or SN270B connected to MTDM-2 ____________________ (equipment location)
• TN754 or SN270B connected to MTDM-3 ____________________ (equipment location)
• TN754 or SN270B connected to MTDM-4 ____________________ (equipment location)
• TN742/TN746B or SN243B connected to 2296A-1 ____________________ (equipment location)
• TN742/TN746B or SN243B connected to 2296A-2 ____________________ (equipment location)
• TN742/TN746B or SN243B connected to 2296A-3 ____________________ (equipment location)
• TN742/TN746B or SN243B connected to 2296A-4 ____________________ (equipment location)
NOTE
On System 75, Generic 1, or Generic 3, lines (or stations) and trunks can reside on the same
board for analog circuits. For digital circuits, lines and trunks should not reside on the same
pack or the modem-pool setup may experience difficulty.
On System 85 or Generic 2, only modem-pooling trunks can be assigned to one analog or
digital board (you cannot mix trunks and lines for modem-pooling circuits).
System 75, Generic 1, and Generic 3 Administration
Use the following steps to administer the switch for modem pooling:
1. Using change system-parameters feature, set Off-Premises Tone Detect Timeout
Interval to 25 seconds.
2. Using add modem-pool next (for System 75 or Generic 1) or add modem-pool xxxx (for
Generic 3, where xxxx is the next available number), set Group Type to combined and press
ENTER . The screen will be filled in as shown in Figure 11-8, System 75, Generic 1, and Generic
3 Modem Pool Assignments.
Make the entries as shown. Analog and digital assignments correspond to the equipment locations of
the TN742 or TN746B and the TN754 circuits, respectively. When all entries are made, press
ENTER .
