| Function and Feature | |
| Synchronous/Asynchronous transparent data port | Not supported |
| External clock port | For TNF1AUX:
Uses one RJ45 port providing two BITS clock inputs and two clock outputs. The port impedance is 120 ohm. The two clock inputs can use independent clock sources but the two clock outputs must use the same clock source. A site can use only one clock source at a time. |
| External time port | The TNF1AUX board provides two external clock input/output ports with TOD0 and TOD1 ports. |
| Housekeeping alarm input/output ports | Provides alarm ports with six inputs and two outputs. |
| Outdoor cabinet monitoring port | Supported. |
| Orderwire phone port | Provides one orderwire phone port so that operation/maintenance engineers at different workstations can have voice communication with each other. |
| Specifications of orderwire ports | |
| Transmission channel | Bytes E1 and E2 in the SDH overhead
