Planning for installation
Use the following forms to plan port and station assignment:
"Remote Office 9150 Configuration Information—Stations" on page 428
"Meridian Internet Gateway Reach Line Card Connection Information—16
ports" on page 444
"Meridian Internet Gateway Reach Line Card Connection Information—32
ports" on page 449
To implement circuit-switched mode
In a network using circuit-switched mode only, all incoming and outgoing calls
are processed through the PSTN
to or from the host PBX (host-controlled mode)
to or from other PSTN customers (local-controlled mode)
To use this scenario, follow these steps:
1 Determine how many simultaneous calls you want to process over the
circuit-switched network. 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 437.
Similarly, you must calculate how many DSP application modules to install
on the MIG RLC (if any), using the "Meridian Internet Gateway Reach Line
Card System expansion worksheet" on page 458.
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 MIG RLC, if needed.
Note: The Remote Office 9150 unit does not ship with trunk interface
modules or DSP application modules installed. The MIG RLC does not ship
with DSP application modules installed.
