VOP1372G-61
Overview
The VOP1372G-61 line card is designed to install with IES-6000/5112/5106M.
VOP1372G-61 provides aggregated 72 lines of Plain Office Telephone Service toward
PSTN network. Each telephone line interface, Foreign Exchange Subscriber (FXS)
connected with subscriber’s telephone set through copper wire ranged up to 5km.
The analog voice signal from subscriber was converted to packet voice and
transmitted toward called party through packet network. FXS line card uses H.248
protocol for network signaling to establish a voice call. Advance call features like
‘three-party conference call’, ‘call forward”, “call waiting”, etc. are integrated in the
Media Gateway Controller (MGC) to make NGN migration become easy in access
network deployment and management. Besides, to consider simplify access network
convergence toward unified IP packet network, FXS line interface can co-exists with
deployed ADSL or VDSL service in the same paired copper wire without disturbing
each other.
