11.1.1 Functions and appearance

Panel
The 16MULTI card, a multi-service access card, supports up to 8
FXS/FXO voice interfaces, 4E&M audio interfaces, and 4 data
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
can be configured according to the DIP switch.
–
The Tx D/A gain ranges from -23 to +7 dB, and its default value
can be configured according to the DIP switch.

Support E&M signaling mode of TYPE5.
 Support internal loopback for E&M signaling.

Support V.24 and RS485 data modules and provide up to 4 ways of
data access. The data interface uses a HDB26F connector and is
marked with "DATA".
 Support configuring V24 interface to synchronous mode (V.24) or
asynchronous mode (RS232).
 Support configuring RS485 interface to full duplex mode (RS422) or
half duplex mode (RS485).
 Support configuring interface bandwidth to 64 kbit/s or 128 kbit/s.
 Support internal and external loopback on data interfaces.
 Support lightning protection and overcurrent protection
 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
details, see Table 11-1.
