January 2005 Planning for Remote Gateway 9150 unit installation
Adding trunk interface modules
Initially, the Remote Gateway 9150 unit ships with no trunks. As connection
needs change, you can add up to four ISDN BRI S/T or U trunk interface
modules.
To determine how many trunk interface modules you need to install, use the
“Remote Gateway 9150 System expansion worksheet” on page 385. For
instructions on installing or replacing existing trunk interface modules, refer to
“Installing trunk interface or DSP application modules” on page 93.
