3COM 3C8951B NBII WAN EXTENDER 2 T1 PORTS

3Com's NETBuilder II WAN Extender acts as a high-density ISDN interface for a NETBuilder II bridge/router, providing many central-site channels for digital dial and channelized leased circuit connections. Each data channel represents an independent communication path to a bridge/ router at a remote site and is seen as a unique "virtual" port by the NETBuilder II. With convenient software updating via a PCMCIA memory card, easy system monitoring through multiple LEDs, and high-speed, high-bandwidth processing, WAN Extender delivers a powerful boost to NETBuilder II WAN connections.
