M3901 digital telephone set support
Remote Gateway 9100 Series allows you to use M3901 digital telephone sets for
local (locally controlled) calls or for remote (host-controlled) calls, not both. For
local (locally controlled) calls, configure the digital telephone set as an M3901
at both the remote unit and the host PBX. For remote (host-controlled) calls,
configure the digital telephone set as an M3901 at the remote unit and as an
M3902 at the host PBX.
Footstand
Installation of a Remote Gateway 9110 unit or a Digital Telephone Internal IP
Adapter unit requires an Analog Terminal Adapter/Meridian Communications
Adapter (ATA/MCA) footstand. Meridian Modular Telephones (M2000 series)
with a date code of May 6, 1998 or later come equipped with the required
footstand. Contact your Nortel distributor to obtain the necessary footstand if
your telephone has an earlier date code.
Data channel adapters
The Remote Gateway 9150 unit supports the following types of data channel
adapters:
„
Analog Telephone Adapters (ATAs)
Note: The Remote Gateway 9100 Series systems using ATAs do not
support modems.
„
Meridian Communication Adapters (MCAs)
Note: MCAs use the secondary data channel of the TCM telephone interface
and require a full 64 Kbps of bandwidth. If you have a 56 Kbps connection,
ensure that this connection provides multiple B-channels. Refer to
“Understanding port relationships” on page 110 for information about port
assignment for data channel adapters.
A 16-port RLC handles up to four data channel adapters. A 32-port RLC handles
up to seven data channel adapters.
Note: Remote Gateway 911x units and Digital Telephone IP Adapters do not
support data channel adapters.
