Configuring the Remote Gateway 9150 unit
Local and remote call capability
Stations defined as Local and Remote are associated with RLC ports, and can
place and receive calls through both the host PBX and the local PSTN
place calls to other stations at the Remote Gateway 9150 site
Outgoing calls are routed according to the call appearance key used to initiate
the call.
Calls initiated on the key defined as the host call appearance key (also
referred to as the primary DN key) are routed through the host PBX.
External calls initiated on the key defined as the local call appearance key
are routed through the local PSTN.
Internal calls initiated on the local call appearance key are routed to other
stations at the Remote Gateway 9150 site.
The Remote Gateway 9150 unit distinguishes an incoming call by its calling line
identification, and rings it as follows:
on the host call appearance key if the call was routed through the host PBX
on the local call appearance key if the call was routed through the local
PSTN or if the call was a station-to-station call

station to:
enable or disable certain features (for more details, refer to "9150 port
configuration" on page 207)

Sequence" on page 212)
identify local call appearance and feature key positions (refer to "Optional
Feature Keys" on page 213)
Remote station settings
When the station is defined with remote capability, you can assign it to a
specific port on the RLC (refer to "9150 port configuration" on page 207).
