It supports a line loop resistance of 1000 Ohms, which includes the resistance of the terminal equipment. It allows stations to be 2.6 cable kilometers (1.6 cable-miles of #26 American Wire Gauge [AWG] cable) from the system.
The SLMAC board generates its own ringing voltage and does not require an external ring generator. It supports V.90 (56K) modems with data transmission rates up to 50 kilobits per second (Kbps)
The SLMAC board has SIPAC shelf connectors.
