To implement circuit-switched mode
In a network using circuit-switched mode only, all incoming and outgoing calls
are processed through the PSTN
n
to or from the host PBX (host-controlled mode)
n
to or from other PSTN customers (locally controlled mode)
To use this scenario, follow these steps:
1 Determine how many simultaneous calls you want to process over the
PSTN. This will help you determine how many trunk interface modules and
DSP application modules to install on the Remote Office 9150 unit.
To do this, complete the "Remote Office 9150 System expansion
worksheet" on page 355.
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
(NTP 555-8421-210)
2 Arrange for ISDN BRI lines from the PSTN to the Remote Office 9150 site,
if they are not already present.
3 Install ISDN BRI trunk interface and DSP application modules on the
Remote Office 9150 unit, if needed. Up to four ISDN BRI modules and up to
three DSP application modules can be installed.
Similarly, install DSP application modules on the RLC, if needed.
Note: The Remote Office 9150 unit does not ship with trunk interface
modules or DSP application modules installed. The RLC does not ship with
DSP application modules installed.
4 Obtain the ISDN BRI information for each line from the Remote Office 9150
site's PSTN service provider. This information must be configured on the
Remote Office 9150 unit.
