Planning for installation
Adding trunk interface modules
Initially, the Remote Office 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 Office 9150 System expansion worksheet" on page 355. For
instructions on installing or replacing existing trunk interface modules, see
"Installing a trunk interface or DSP application module" on page 100.
