• PCM Idle Pattern: This pattern will be sending on each B channel PCM
time slot when the channel is idling (not connected). The default value
for A-Law is 0xff and for Mu-Law is 0x55. You only change it when
SWITCH need.
• CAS Idle Pattern: When channel is idle, ABCD (CAS) pattern to be
applied CAS signaling bus
• Jitter Min Delay: The minimum delay time of Jitter buffer. The range is 0
to 150ms. Default value is 150ms. Which has better voice quality but the
delay time will be long.
• Jitter Opt Factor: Jitter buffer optimization factor from 0 to 12. The
default value is 7. Set to 0 will have lowest voice delay but have bad
voice quality. Set to 12 will have long voice delay but with better voice
quality
• EC Tail Length: Echo Cancellation Length, default value is 32ms
• Silence Compress: Enable silence compress or not
• TDM Bus Clock: TDM Bus clock source
o
Internal: The TDM bus clock will be derived from internal oscillator.
Use it when all trunks’ clock is set to internal only.
o
External: The TDM bus clock will be derived from external PSTN
E1/T1 clock. When some of trunks are set to internal and some are
set to external, please set to external and specified a trunk which
clock is external as the TDM bus clocking in local reference.
• Detect Fax Mode: T.38 fax detecting method
o
Answering Fax only: Detect answer tone to initiate T.38
o
Fast Fax Detect: Detect calling and answer tone for T.38. Use
Answering fax only when fast fax detect miss detect a fax call.
• Auto Clock: Automatic detect trunk clock source. It is recommended to
specify clock source.
• Local Reference: TDM bus reference clock. Please set to a connected
trunk.
• Overlap Digit: Enable Q.931 overlapping sending or not.
• DTMF Interval (Millisecond): Wait overlap digits time out
• CAS Send Restart: When channel is blocked, send restart or not.
• Reset Trunk When Link Up: When trunk is started, restart channels or
