The UCM6510 supports E1/T1/J1 which are physical connection technology used in digital network. T1 is
the North American standard, J1 is used in Japan, whereas E1 is the European standard.
UCM6510 supports four signaling protocols: PRI, MFC/R2, SS7, E&M Immediate and E&M Wink. PRI
provides a varying number of channels depending on the standards in the country of implementation (E1,
T1 or J1); MFC/R2 is a signaling protocol heavily used over E1 trunks; SS7 uses out-of-band signaling,
which travels on a separate, dedicated channel rather than within the same channel as the telephone call,
providing more efficiency and higher security level when the telephone calls are set up. E&M Immediate
and E&M Wink are only valid when using T1 port.

1. Go to web UI->PBX->Ports Config->Digital Hardware to configure port type and channels.
2. Go to web UI->PBX->Basic/Call Routes->Digital Trunks to add and edit digit trunk.
