What is acTrunkLineCode?

Selects line encoding (B8ZS, AMI for T1; HDB3, AMI for E1) to ensure signal integrity over physical trunk wires. Network operators set this to match carrier specifications and prevent bipolar violations that corrupt data. B8ZS (value 0) is the standard for T1 trunks in North America.
