How the RLC works
When a call comes through the host PBX to a user at a remote location, the RLC
makes a connection to the appropriate remote unit. The host PBX completes the
call. If the RLC cannot establish a connection, the call rings until the host PBX
forwards it to voice-mail.
Initiate outgoing calls by either picking up your telephone’s handset or pressing
a line appearance key. There are two types of appearance keys:
„
host call appearance keys, used to place calls to the host site
„
local call appearance keys, used to place calls to another station at the
branch office, or to place and receive calls through the local PSTN
The diagrams and procedures on pages 30–34 present the details of the outgoing
call process.
RLC processing modes
The RLC processes calls for a Remote Gateway 9100 Series network in one of
two modes:
„
host-controlled
„
locally controlled
Host-controlled calls
When you place a call to someone at your host site, or when someone at your
host site calls you, the call is processed in host-controlled mode. The RLC routes
such calls through the host PBX. The diagrams and procedures on pages 30–33
present the details of host-controlled call processing for the Remote Gateway
9150 unit.
