DEC WANCcontroller 220 (DSB32)
VAXBI Synchronous Communications Controller

Expand your VAXBI Synchronous Communications

The DEC WANCcontroller 220 (DSB32) is a two-line synchronous
communications controller designed specifically for Digital’s VAXBI
systems. It provides direct connection to VAXBI environments for

public data networks, private corporate networks, and local hardwired links, insuring optimum performance and reliability.
Computer-to-computer communications or computer-to-network
communications are facilitated with the DSB32. Communications can
be established with X.25, DECnet, and IBM networks by using Digital
standard layered software.

The DSB32 provides up to two lines for VAXBI communications

access. Since these lines are independently controlled, different
protocols can run simultaneously on each of the two lines.

The DSB32 consists of a module and a cabinet kit. The module

contains a 32-bit communications microprocessor with the power of
VAX architecture. The cabinet kit includes a distribution panel with
two 50-pin line connectors and four ribbon cables to interconnect the

module and panel. Adapter cables connect the panel’s line interfaces
and provide compatibility with the desired interface standard.
Extension cables connect the adapter cables to the transmission
interfaces, e.g. modems. Adapter and extension cables must be
ordered separately.
