interfaces. It provides the following functions:
Provide 2 voice modules: FXS and FXO, and provide up to 8
FXS/FXO interfaces, which use 2 RJ45 interfaces and are marked
with "VOICE".
Support configuring voice gain through software on FXS/FXO
interfaces:
–
The A/D gain ranges from -3 to 13 dB, and is 0 dB by default.
–
The D/A gain ranges from -13 to 3 dB, and is 3.5 dB by default.
Support internal and external loopback on FXS/FXO interfaces.
Provide 4E&M interfaces which use a HDB26 connector and are
marked with "E&M".
Support 2/4 wire configuration on E&M interfaces.
Support configuring voice gain through software on E&M interfaces:
–
The Rx A/D gain ranges from -10 to +19 dB, and its default value

Support assigning timeslots as below:
–
For 8 ways of voice, each way occupies one timeslot in turn fixedly
of TS0–TS7.
–
For 4 ways of E&M voice, each way occupies one timeslot in turn
fixedly of TS8–TS11.
–
For 4 ways of E&M voice, each way occupies two timeslots. For
