Enterprise FXS concentration and extension over IP and T1/E1

The SN4900 Series IpChannel Bank can be used with a T1/E1 gateway to extend a T1 or E1 line over IP and split it into FXS ports—providing operators and enterprise network administrators with a simple and cost- effective option to provide a large number of FXS ports in a remote location (see figure 5).

Bulk analog line extensions

The SN4900 FXO and FXS models used in combination enable enterprises to extend up to 32 analog phone lines over any IP link – be it the public Internet, a leased line or a WiMax link. 600kBit/s bandwidth are enough for 32 simultaneous voice or fax conversations, using G.723 compressed voice transmission.

Advanced quality of service (QoS) features ensure optimal bandwidth usage and voice quality, even on small band- width links and with simultaneous transport of data or VPN traffic between the SmartNodes.
