16.2.1.2 E1 Mode
In E1 mode, TS16 carries the signaling information. This information can be in either CCS (common
channel signaling) or CAS (channel associated signaling) format. The 32 time slots are referenced by two
different channel number schemes in E1. In “Channel” numbering, TS0–TS31 are labeled channels 1
through 32. In “Phone Channel” numbering, TS1–TS15 are labeled channel 1 through channel 15 and
TS17–TS31 are labeled channel 15 through channel 30.
