You can use this modular structure to do the following:
• install modules on different computers in the TCP/IP network
• set up a standby eKERNEL on a second site
• connect more than one DMC to DECT Messenger
DECT Messenger in a WAN or MAN network
DECT Messenger can be used in a multiunit MAN (IMP network), or in a multinode WAN
(DPNSS network). If DECT Messenger is installed in a multiunit DMC network (MAN), you can
send LRMS (E2) messages to DECT handsets in units other than those in which DECT
Messenger is connected. The IMP links support LRMS (E2) messaging, but this generates a
heavy load on the interunit links. Therefore, Avaya recommends that you avoid sending LRMS
(E2) messages over interunit links. If you must send LRMS (E2) messages to handsets in a
unit other than the one having the DECT Messenger connection, Avaya recommends that you
make a direct DECT Messenger connection to those other units, as well.
Figure 15: DECT
Messenger in a multiunit or multinode environment on page 64 shows a configuration in
which DECT Messenger has connections to more than one DMC. The connection between
the units can be either an interunit (IMP) link (MAN) or a DPNSS connection (WAN), because
there is no messaging passing through the links between the units.
Figure 15: DECT Messenger in a multiunit or multinode environment
Figure 15: DECT Messenger in a multiunit or multinode environment on page 64 shows a
multiunit or multinode network. DECT Messenger must be able to send messages to DECT
handsets in Unit X/Node X and Unit Z/Node Z. On the DECT Messenger computer (Area 1),
the eKERNEL is running with other modules and an eDMSAPI to send messages to Unit X/
Node X. The second computer (Area 2) provides messaging to Unit Z/Node Z. DECT
Messenger contains a table that provides data about the location of the DECT handsets. If
