Voice over IP network call
1 The Remote Gateway 911x user lifts the handset (item A).
Result: The Remote Gateway 911x user hears a dial tone. This indicates a
successful connection to the RLC over the IP network and the corporate
WAN (item B).
2 The Remote Gateway 911x user dials the external telephone number.
Result: The Remote Gateway 911x series unit sends the dialed digits as
packets across the Ethernet network. The packets go through the IP
network and the corporate WAN, to the RLC. The RLC converts the
packets to the format required by the host PBX. The host PBX then
converts the data to voice and routes the call through the PSTN to the
called party (items C and D).
PSTN call
1 The Remote Gateway 911x user lifts the handset (item 1).
Result: The Remote Gateway 911x user hears a dial tone. This indicates a
successful connection to the host PBX over the PSTN (item 2).
2 The Remote Gateway 911x user dials the external telephone number.
Result: The Remote Gateway 911x series unit sends the dialed digits
across an analog line through the PSTN, through the host PBX to the called
party (items 3 and 4).
Note: Item notations in parentheses refer to circled markers in the diagram on
page 38.
