What is the Tenor BX?
The Tenor BX is a high-density VoIP (Voice over Internet Protocol) H.323/SIP switch that converts
voice, fax, and modem data on digital circuit switched trunks, and transmits it over the IP network.
The Tenor BX is suitable for small to medium enterprises and service provider applications by sup-
porting 2, 4 or 8 BRI (Basic Rate Interfaces (2B+D channel) ports with S/T interface, supporting up
to 16 voice channels.
Depending on the port configuration, the Tenor BX is available in two configuration types:
• MultiPath Switch (intended for PBX, PSTN and VoIP connectivity)
• Gateway (intended for VoIP and PSTN trunk port or PBX connectivity)
The MultiPath Switch is mainly intended for symmetrical multipath applications. The number of
VoIP channels is equal to half the number of PSTN channels. The MultiPath Switch configuration
enables connectivity between the customer equipment (i.e., PBX), PSTN and VoIP Network. The
Gateway is mainly intended for trunking applications interfacing between the VoIP network and the
circuit switched network (PSTN). The number of VoIP channels equals the number of PSTN chan-
nels.
