in motorola, 1 RSL = 1 BTS ? this is very surprising… normally, 1 RSL = 1 TRX. And it is possible to put 4 RSL on 1 Abis TS (64kbps), or it is also possible to multiplex the RSL within the TRX’s 2 Abis TS.

How can motorola carry the signalling of one BTS of 15 TRX through only 64kbps ? do you know the trick ?

why 120 ohm we use in signalling.

[Abdel]

Hi nandan,

120 ohm transmission can be used for both voice, data or signalling and not only for signalling. In telecom 50, 75 and 120 ohms are used. the 50 ohm is mostly used for RF transmission.
