CS1K Serial TTY cables

Cisco Console cable adapter pinouts for CS1K applications.

Instead of carrying several different dedicated CS1K TTY cables, one solution is to use a standard Cisco Console cable with a few custom adapters. Find a blue Cisco Console cable (like the one on the left), and build the following RJ45 to D-type shrouds (like the ones on the right) to cover all your CS1k TTY cable needs.
