8.6.1 Functions and appearance

Panel
The Audio is a 16-way FXS/ FXO /magneto telephone access card. It provides the following
functions:
 Support 16 voice interfaces. The voice interface types are specified as FXS, FXO, and
magneto telephone.
 Every 2 voice interfaces use 1 voice module. Each voice module supports being specified
as one of FXS, FXO, and magneto telephone.
 The voice gain is adjustable. Its step is 0.1dB:
–
–
–
 Support configuring signaling occupation bits: a-bit and b-bit. By default, it is a-bit.

The voice interface and ringing output support overcurrent protection.
 Magneto telephone supports detecting and generating the 2100 Hz audio.
 Support E1 timeslots from TS0 to TS15 occupied by 1 to 16 ways of voice services on the
backplane.

Support online upgrade.

Support configuring signaling mode to RAISECOM, user-defined mode, or other mode.
By default, it is RAISECOM.
The Audio card is used with E.40 or later RC3000-15-DXC.
Avoid short circuit when the Audio card is running. If short circuit occurs and
ringing lasts over 10 minutes, the Audio card will be damaged.
Do not insert and pull out the voice module. For hardware operations on the voice
module, contact Raisecom technique support engineers. Hot swapping the voice
module is forbidden under any condition; otherwise, the Audio card and RC3000-
15 will be faulty.
If a voice module fault occurs, the Raisecom technical support engineer need to
notice the following matters:


FXS/FXO/ magneto telephone Rx (A/D) gain ranges from -10 to 16 dB. By default, it is
0 dB.
FXS/FXO Tx (D/A) gain ranges from -13 to 10 dB. By default, it is -3.5 dB.
Magneto telephone Tx (D/A) gain ranges from -17 to 8 dB. By default, it is -3.5 dB.
When the voice module on the Audio card is faulty, rebooting the RC3000-15 or
inserting and pulling out the Audio card will clear configurations about all
interfaces and cross connection (you can use the normal voice module again by
re-configuring the card.); if rebooting the RC3000-15 or inserting and pulling out
the Audio card is not executed, the current service of other voice modules will
not be influenced.
When the voice module on the Audio card is faulty, if there are normal voice
modules connected to an interface neighboring to the interface with the faulty
one (for example, the voice module on No. 2 interface is faulty, but the one on
No. 3 interface is normal), at this time, you can configure normal voice modules
through the NMS or CLI. In this case, you cannot delete the NE which the Audio
card is located. Otherwise, you cannot configure the Audio card through the
NMS even though you re-add the NE.
