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.

Note: If channels are not recognized as off-hook even though the voice system has stopped, change the Idle Code to 11111111. This is a known issue with DS1 connectivity to MultiVantage S8300.

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 Trunk stops working.

Values: none, 1, 2 (for dual port cards); none, 1, 2, 3, 4 (for quad port cards).

Fax Enabled?

The availability of fax with the protocol.

Values: yes, no.

Country

The country that the system is in.

Values: Brazil, Canada, Germany, France, Great Britain, Ireland, Italy, Korea, Mexico, United States.
