For E1 PRI, 16th channel(015) would be the BChannel which is why the ISDN serial interface id would contain: 15 and this cannot be altered. It is: 23 in case of T1 PRI as 24th Channel(023) is the BChannel.
The Basic Rate Interface consists of two 64 Kbps Bchannels and one 16 Kbps Dchannel. Thus, a Basic Rate Interface user can have up to 128 Kbps service. The Primary Rate Interface consists of 23 Bchannels and one 64 Kpbs Dchannel using a T1 line or 30 Bchannels and 1 Dchannel using an E1 line.
