Operating Procedure

No manual operation is required.

Service Conditions

FCCS over IPTRK

To send/receive voice information, each node shall use IPTRK circuit card(s). At this time, the IPTRK

cards in the self-node and its connected node(s) can be either in 1-to-1 ratio, respectively (called point-to-

point connection), or in 1-to-n [n=2 or more] relations (called point-to-multipoint connection). For point-

to-point connection, FCH-FGH card is used for FCCS signaling.

Be sure to place a router for connections between IP network and IPTRK/FGH card.

A maximum of 2 IPTRK cards per unit can be installed. Accordingly, a total of 16 IPTRK cards can be

accommodated per IMG.

Only voice and FAX (G3) information can be sent/received via IPTRK card.

Only a single FCH-FGH card can be connected to a router (i.e. an FCH-FGH, connected to a router, cannot

control the IPTRK card(s) connected to the other router). Accordingly, redundant configuration of FCH-

FGH is not available.

A call cannot be established/routed across multiple IP networks. See the figure below:

When multiple IPTRK cards are used for node-to-node connection and all the lines on an IPTRK are busy,

alternate routing is available (see the following figure). However, if a router or FCH-FGH card cannot be

used, all the related IPTRK routes are also made unavailable.

As shown, when multiple IPTRKs exist, alternate routing is available:

Alternate Routing: OK

When using IPTRK card for point-to-multipoint connection, the port, assignable for FCCS signaling, is

the 1st LEN of each HW block. Other ports are to be used for speech channels.

For point-to-multipoint connection, a D-channel, assigned on an IPTRK card, can control the B-channels

of the same card, and also of a maximum of 7 other IPTRK cards.
