Dear all,
We have an rp4440 server with a J3525A PSI card and connected through a X.21 Cable to a Cisco router. We currently have a failed cable and require the pin assignment of that cable. Can anyone provide it please? thank you

Hi
J3535A is also an PCI card for a rp4440 that supports these cables configuration:
Serial RS-232 ├в ┬в V.35 ├в ┬в V.24 ├в ┬в X.21 ├в ┬в Serial RS-449 ├в ┬в V.11
X.21 ( occasionally written as X21 )is a specification for differential communications that that includes the definition of connector pin allocations. It is used together with V.11 to define a specification for serial synchronous communications at up to 10Mbps. A variant of X.21 called 'circuit switched X.21' is now no longer in use except for a few legacy systems.
