FXS
FXS provides 16 POTS interfaces. It supports DP (Dial Pulse)
and DTMF (Dual Tone Multiple Frequency) dialing modes, and it
adapts ITU-T G.711 standard A-law Companding coding rules and
CAS (Channel Associated Signaling). Its Link Performance
conforms to ITU-T G.712 standards as well as Chunghwa
Telecom’s ME 2401-4 Specifications. With no concentration or
compression, the maximum number of subscriber ports in one
shelf is 256. The maximum number of subscriber lines in one
system, without having to consider concentration or compression
is 1,890, while the number can increase to 7,560 with
concentration or compression.
FXS-P
The FXS-P Module is usually installed within the RT Shelf, and
