Introduction
The QPC513 Enhanced Serial Data Interface (ESDI) card gives the CS
1000E, CS 1000M, and Meridian 1 switch two fully synchronous high-speed
serial ports.
These high-speed synchronous ports are used to connect the processor
to synchronous communication peripherals such as to a host computer
(for example, DEC or Tandem) using Meridian Link. This card cannot be
used as an asynchronous port or to connect to an administrative and
maintenance terminal. Use either the NT8D41 SDI paddle board or the
QPC841 Quad Serial Data Interface card to connect the switch to an
asynchronous serial peripheral.
Each system can accommodate up to eight ESDI cards, for a total of 16
synchronous ports per system. The ESDI cards can be housed in the
network slots of any of the following modules:
•
NT5D21 Core/Network module (slots 0 through 7)
•
NT6D39 CPU/Network module (slots 1 through 9 and 13)
