On this gateway, we have two E1 PRI trunks, thus two voice ports. Each voice port is in the form “slot/subunit/port:signaling channel”.

In the table that comes after each displayed voice port, we have 31 lines. These are the available channels on each PRI link. Notice that the column “CH” refers to timeslot, and not the channel. The 16th timeslot carries the 15th channel, which is the signaling channel (D channel).
