• 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: derived from internal oscillator
o
External: derived from external PSTN E1/T1 clock
• 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 instead of use auto clock.
• Local Reference: TDM bus reference clock. Please set to a connected
trunk.
• Overlap Digit: Enable to receive ISDN/PRI Q.931 overlapping sending
or not.
• DTMF Interval: Wait overlapping digits time out
• CAS Send Restart: When channel is blocked, send restart or not.
• DTMF Volume: DTMF relay volume (default 16: 0 db)
• Active T38 when Open Channel: Re-open DSP channel when T.38 is
started.
• PSTN Show Display Name: Send ISDN display name IE or not
(network side only)
• SIP Show Display Name: Relay ISN display name to SIP or not
• Reset Trunk When Link Up: When trunk is started, restart channels or
not.
