G.703 Interface Options (2 of 2)
Line Framing
Possible Settings: CRC4, noCRC4
Default Setting: noCRC4
Specifies the framing format to be used by the G.703 interface.
CRC4 – CRC4 framing formatting is used for transmitted and received data over the
Network Interface.
noCRC4 – Non-CRC4 framing format is used for transmitted and received data over the
Network Interface.
Time Slot 16
Possible Settings: Signaling, Data
Default Setting: Signaling
Specifies weather the G.703 interface is used for voice or data.
Signaling – Timeslot 16 is used for signalling (the unit is in voice mode).
Data – Timeslot 16 is used for data (the unit is in data mode).
NOTE:
For associated DSL line rates and payload rates refer to Table 3-4,
Fixed
Rate Payload Rates and DSL Line Rates
in Chapter 3,
Initial Startup and
Configuration.
Primary Clock Source
Possible Settings: G.703, Internal
Default Setting: Internal
Specifies where the unit will derive its timing from.
Internal – The clock source is derived from the internal oscillator.
G.703 Pt1 – The clock source is derived from the G.703 interface.
Possible Settings: 1E–4, 1E–5, 1E–6, 1E–7, 1E–8, 1E–9
Default Setting: 1E–4
Determines the error rate at which an excessive error rate (EER) condition is
recognized. The rate is the ratio of the number of CRC errors to the number of bits
received in a certain period.
Send AIS on Network Failure
Possible Settings: Enable, Disable
Default Setting: Enable
Specifies the action taken on the signal transmitted to the G.703 when a valid signal
cannot be recovered from the network interface (LOS or cognitions OOF, AIS, or EER).
Enable – An Alarm Indication Signal (AIS) is sent to the DTE in the event an LOS or
continuous OOF, AIS, or EER condition exists on the G.703 interface.
Disable – The failed signal on the interface is sent to the DTE in the event an LOS or
continuous OOF, AIS, or EER condition exists on the G.703 interface.
