Implementing PSTN mode
In a scenario involving the PSTN mode only, the PSTN processes all incoming
and outgoing calls as follows:
To implement PSTN mode, you must complete the following steps:
1 Determine how many simultaneous calls you want to process over the
PSTN. This helps you determine how many trunk interface modules and
DSP application modules to install on the Remote Gateway 9150 unit.
To do this, complete the “Remote Gateway 9150 System expansion
worksheet” on page 385.
Similarly, you must calculate how many DSP application modules to install
on the RLC (if any), using the “Reach Line Card System expansion
worksheet” in the
Reach Line Card Installation and Administration Guide
(NTP 555-8421-210) .
2 Arrange for ISDN BRI lines from the PSTN to the Remote Gateway 9150
site, if they are not already present.
3 Install ISDN BRI trunk interface and DSP application modules on the
Remote Gateway 9150 unit, if needed. Up to four ISDN BRI modules and
up to three DSP application modules can be installed.
IF the call is to or from the THEN the call is in
host PBX, host-controlled mode.
other PSTN customers, locally controlled mode.
