Digital interfaces protocols screens
The Avaya IR system supports the following digital telephony protocols:
- ISDN-Primary Rate Interface (PRI) T1
- ISDN-Primary Rate Interface (PRI) E1
- Loop Start T1
- Loop Start E1
- Wink Start T1
From this set of screens, you can control which protocols are assigned to cards. You can also change the parameters for each protocol.
Fields
The following fields are displayed by the browser:
- Card � A number that identifies a telephony card
- Clock fallback trunk � The trunk that the Avaya IR system uses to set its internal clock if the timing source on the Clock trunk stops working
- Clock mode � If the telephony board only controls its own clock, then the mode is STANDALONE. This is the only option.
- Clock source � The origin of the telephony board's clock reference. OSC refers to the telephony board's oscillator, and NETWORK refers to the clock extracted from the telephony trunk.
- Clock trunk � Which trunk the board uses for its internal clock reference
- Country (Loop Start E1 only) � Which country the system is in
- D-Channel on trunk (ISDN only) � Whether or not a data channel is available on the specified trunk. Note that yes is the only valid option for ISDN PRI E1.
- Fax enabled? � Whether or not fax is available with the protocol
- Frame type � The frame format. Options include D4 and ESF for ISDN-PRI T1.
- Idle code � A code used in digital communications that represents an absence of data. Options include 11111111, 01010100, and 01010101 for ISDN-PRI T1.
- ISDN type (ISDN only) � The supplier of ISDN service
- Length (T1 only) � The length of the cable between the telephony board and the telephone network. This value should only be changed if the length is more than 200 feet or if there are transmission problems.
- Line code � A replacement for strings of consecutive zeros in data transmission using pulse code modulation (PCM). Options include AMI, AMI_ZCS, and B8ZS for ISDN-PRI T1.
