Field descriptions
Field |
Description |
Frame Type |
The frame format. Values: CEPT. |
Line Code |
The replacement for strings of consecutive zeros in data transmission using pulse code modulation (PCM). Values: HDB3. |
Idle Code |
The code used in digital communications that represents an absence of data. Values: 11111111, 01010100, 01010101. |
CRC |
Cyclical Redundancy Checking (CRC) is an error checking technique that is used to ensure the accuracy of digital transmissions over a communications link. To enable CRC for one or more E1 trunks, select the check boxes for the appropriate E1 trunks. |
Clock Trunk |
The trunk that the board uses for its internal clock reference. Values: 1, 2 (for dual port cards); 1, 2, 3, 4 (for quad port cards). |
Clock Source |
The origin of the board's clock reference. Values: NETWORK, OSCILLATOR. NETWORK refers to the clock extracted from the trunk, OSCILLATOR refers to the board's oscillator. |
Clock Mode |
The control of the board's clock. Values: STANDALONE. The board controls its own clock. |
Clock Fallback Trunk |
The trunk that the system uses to set its internal clock if the timing source on the Clock Source stops working. Values: 1, 2 (for dual port cards); 1, 2, 3, 4 (for quad port cards). |
Fax Enabled? |
The availability of fax with the protocol. Values: yes, no. |
Wait time before answer |
The number of milliseconds that the system waits to answer an incoming call. Values: 0-14. |
Expected number of DNIS digits |
The number of DNIS digits that the system expects to receive. Values: 0-30. |
ISDN Type |
The type of ISDN service. Values: ETSI, QSIG. |
D Channel on Trunk 1 |
The availability of a data channel on Trunk 1. Values: yes. |
D Channel on Trunk 2 |
The availability of a data channel on Trunk 2. Values: yes. |
D Channel on Trunk 3 |
The availability of a data channel on Trunk 3 (quad port cards only). Values: yes, no. |
D Channel on Trunk 4 |
The availability of a data channel on Trunk 4 (quad port cards only). Values: yes, no. |
Impedance |
Applies only to the NMS AG4040 T1/E1 telephony card administered as ISDN-PRI E1 with the ISDN Type field set to QSIG. Values: 120 Ohm, 75 Ohm. |
Enabled Channels |
The number of channels that have been enabled. Values: 0-128 |
PRI Side |
The side from which you want the PRI protocol to function. Set it to user if you want your Avaya DEFINITY or MultiVantage system to behave as the network. Set it to network if you want your Avaya DEFINITY or MultiVantage system to behave as the user. Values: USER, NETWORK |
