Reply To: Lines to T1/E1 conversion

Hi, Taha!

1. Similar to the North American T-1, E1 is the European format for digital transmission.

E1 carries signals at 2 Mbps (32 channels at 64Kbps, with 2 channels reserved for signaling and controlling), versus the T1, which carries signals at 1.544 Mbps (24 channels at 64Kbps). E1 and T1 lines may be interconnected for international use.
It has 32TS (TimeSlot), assigned:
+TS0: for only synchronous purpose. 8 bits is “X0011011”. It indicates the starting point of frame. X- CRC code option.
+TS0-TS15: data channel: voice, fax, v.v… You can used Nx64kpbs.
+TS16: for R2MFC signalling and multi-frame synchonazation. In CCS7 system, TS16 also carriers the data.
+ CCS7 can be carriered in any TS, from TS1-TS31.
2.So, 6 lines = 6 TS.
