OFFICE DATA PROGRAMMING

7.For Point-to-Multipoint connection, one IPTRK circuit card (assigned as FCCS signal controlling card by the AFCH command), can control the B-channels of the same card, and also a maximum of 15 other IPTRK circuit cards. It is not necessary to assign the trunk data for a time slot as a controlling channel.See the following figure.

When the connection is Point-to-Multipoint, port accommodation for the IPTRK circuit card is shown below. All the available time slots on the controlling IPTRK circuit card can be assigned as the B-channel.

Note 1: The IPTRK circuit card can be accommodated in the shaded slots (a maximum of two cards per UNIT). HW indicates Highway Block.

Note 2: Be sure to assign a B-channel in the first time slot of the controlling IPTRK circuit card.

8.During IPTRK circuit card-related tandem connection, speech quality can become poor, or dual connection failure may occur. DTMF and FAX relay cannot be used.

9.Any service that is not available for the FCCS network, is not available utilizing this service.

10.This feature supports QoS (Quality of Service) function.

11.When a system message indicates “TCP link failure” due to data congestion on the router or IP network, a call cannot be made via an IPTRK circuit card. When a call is attempted despite this, the caller hears busy tone.

12.When a system message, related to “TCP link failure”, is created during call origination or speech, that call’s speech channel is automatically restored via patrol function.
