TRUNKS
GXW450X is a VoIP Digital Gateway that supports both trunk modes Digital and VoIP to ensure a smooth
integration of digital and VoIP communication to connect the legacy telephony infrastructure made up of
PRI (E1, T1, J1) to the IP network.
Digital Trunks
The GXW450X supports E1/T1/J1 which are physical connection technologies used in digital network. T1
is the North American standard, J1 is used in Japan, whereas E1 is the European standard. GXW450X
supports four signaling protocols: PRI_NET, PRI_CPE, MFC/R2 and SS7. 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.
