    Generally ,Ports denote no. of Time Slots /64 Kbps channels available in a switching system. Out of these total available ports some are reserved for internal communication in switch, some are used for providing service circuits like Tones/Announcements and remaining are used for Traffic Channels (Sub Lines and Interexchange Trunks).

    John,

    Usually we call port to T1/E1, for example 4-port E1 card, or 4-port T1 card.

    Which means, the card support 4 T1/E1 lines, each of 1.56/2.1 Mbps lines, with-in each of switch there will be 24/32 channels…………

    And each channel is a time-slot, which has a speed of 64kbps……

    The ISUP CIC field refers to channel/time-slot…….

    -Hoe this helps…….
