ah that’s advanced you used E1 in an application now, that’s how it is in GSM the like. that’s true with the wireless applications..

so how about concentrated, uncon and multiplexing? how is it done?

heheh

lets do it like this…
PSTN
1 TDMA frame of, be it E1 or T1 its still 64kbps… so usually 64kbps for a voice call in PSTN that’s why you have a 52kbps modem which is under 64kbps…

GSM
1 TDMA frame is divided into 4 TS + another 4TS from the next TDMA frame and you will come up with the GSM’s 1 TRX which is 8TS ~ 7 to 8 VC..
