TN801B MAPD (LAN gateway interface)
Issue 6 February 2007 245
TN801B MAPD (LAN gateway interface)
The TN801 LAN gateway interface is part of the Multiapplication Platform DEFINITY (MAPD).
The TN801 allows direct integration of PC-based applications into the switch. The TN801 circuit
pack works as the interface for solutions such as Computer Telephony Integration (CTI) and
Adjunct-Switch Application Interface (ASAI). The TN801 circuit pack provides:
● packet bus and TDM-bus interfacing,
● physical mounting for a CPU,
● external interfaces, and
● mapping of circuit-switched connections between the TDM bus and the expansion circuit
pack.
TN802B MAPD (IP interface assembly)
The TN802 IP interface circuit pack supports voice calls and fax calls from the switch across a
corporate intranet or the Internet. This circuit pack is still supported, but is now replaced with the
TN2302AP IP media processor
on page 256. The IP trunking software runs on an embedded
PC that runs Windows NT. The TN802 circuit pack supports IP Solutions, including IP trunking
and MedPro (H.323) with IP softphones.
The TN802 IP Interface operates in two modes, IP Trunk and Media Processor (MedPro/
H.323). The TN802 defaults to IP Trunk mode. To use the TN802 in MedPro mode, you activate
it through administration to use the H.323 trunking feature. MedPro mode is necessary to
support IP softphones.
TN1654 DS1 converter, T1 (24 channels) and E1 (32
channels)
The TN1654 converter installs in place of the conventional fiber. The TN1654 converter
supports from one to four T1 or E1 facilities. The TN1654 also provides a total of 92 T1
channels, or 120 E1 channels. These channels run each direction between the processor port
network (PPN) and an expansion port network (EPN). This capacity is enough for the EPN to
easily support several hundred stations.
The switch architecture provides for EPNs that are remotely located from the PPN. An EPN that
is within 5 miles (8 kilometers) of the PPN can be coupled using multimode fiber-optic cable.
