Introduction TXPORT MultiPro platforms are the ideal branch office wide area networking
solution for mainframe computing environments migrating to client/server
LAN-based computing. TXPORT now offers a complete family of frame relay
access equipment, ranging from the branch office 9100 series to high-performance
and high-density central site equipment. Combined with an award-winning line of
WAN access equipment, TXPORT provides total solutions for all your networking
needs.
The TXPORT 9211 MultiPro platform provides four serial ports that are software
configurable for RS-232 and V.35 networks as well as WAN connections with
speeds up to 2.048 Mbps. The TXPORT 9211 MultiPro platform has all the
advantages of a single 9000 MultiPro card in a stand-alone chassis similar to the
9101 and 9111.
The TXPORT 9111 MultiPro platform combines LAN and legacy protocols over
X.25 or frame relay without sacrificing response time or reliability. Three standard
serial ports and an integrated CSU/DSU; either an Ethernet or dual RS-232 option;
and a T1 or DDS option accommodate a wide range of networking configurations.
The TXPORT 9101 MultiPro platform provides a way to run LAN protocols over
X.25 or frame relay without sacrificing response time or reliability. An Ethernet
LAN interface along with an integrated CSU/DSU, and additional serial port
option accommodate a wide range of networking configurations.
The TXPORT 9000 MultiPro card provides four ports configurable for RS-232 and
V.35 user connections as well as WAN connections at speeds up to 2.048 Mbps.
The 9000 MultiPro card mounts in both the three-slot 6400 and eight-slot 6800
chassis.
These chassis are designed for high-density regional and central site installations
requiring Frame Relay or X.25 network access. The 6400 chassis supports up to 12
ports and the 6800 chassis supports up to 32 ports.
TXPORT MultiPro platforms support all major legacy protocols including
SNA/SDLC, Poll/Select, and Bisync and are configurable for asynchronous
connections as well. For the branch office where simple LAN connectivity is
required, the 9101 is the ideal solution to support branch office routing of TCP/IP
and IPX protocols using industry-standard RFC 1490. Multiple LAN protocols can
also be transparently bridged over the network utilizing the Spanning Tree Protocol
per 802.1d. Where LAN and legacy protocols exist together, all network traffic can
be sent over a single frame relay connection.
