The SLMO (Subscriber Line Module, UPN Interface) module supports line termination (LT) for two-wire, digital interfaces in accordance with the UPN method. This interface is a cost-optimized variant of the digital standard interface UP0 . Each UPN interface is an ISDN basic access (BA) with two B-channels (64kbit/sec each) for voice/data transmission and one D-channel (16 kbit/sec). Terminals with UPN interfaces and terminals with S0 interfaces can be connected to the D-channel directly or via a TA-S0 (Terminal Adaptor S0 in a UPN terminal) respectively. A maximum of two terminals plus supplementary equipment can be connected to each port.
The two B-channels can be switched through to any time slot of the system-side PCM highways. Of all possible D-channel data types (s, p, t), only the s-data (signaling) is processed. It is not planned to support p-data (packet switching) or t-data (telemetry).
Provision is made for remote feeding via the UPN interfaces.
