Meridian Link Release 5C/CCR Release 3C Installation and Upgrade Guide
Installing an ESDI or MSDL card
On the Meridian 1, a QPC513 ESDI card (vintage G or later) or NT6D80
MSDL card must have an available port. If there is no ESDI/MSDL port
available, install a QPC513 ESDI or NT6D80 MSDL card before the IPE
Module or the Application Module is configured.
Note: If using a redundant Meridian Link, an additional port is
required for the AML to connect the redundant Meridian Link Module
to the Meridian 1.
1 Unpack and inspect the card.
2 ESDI card onlyÑset the faceplate switch to DIS.
3 ESDI card onlyÑset the jumpers and switches as follows:
¥ Set the jumpers for the appropriate port to reflect DCE and
RS-232 operation, as shown in Figure 40.
¥ Set the port address switch S2 to indicate the device number, as
shown in Table 40.
The location of the switch is shown in Figure 41. The device
number should match the value configured in LD 17 (either the
ADAN prompt in X11 Release 17 or X11 International Phase 7,
or DNUM prompt in X11 Release 18 or later software). Use
LD 22 to obtain a printout of the ADAN information. See
Chapter 12, ÒMeridian 1 configuration for Meridian Link/CCRÓ for
LD 17 configuration.
4 MSDL card onlyÑset the switches as follows:
¥ Set the switches to reflect RS-232 operation, as shown in
Figure 40 and Table 39. (DCE operation is configured in
software for RS-232.)
¥ Set the physical card address switches (ÒTensÓ and ÒOnesÓ) to
indicate the device number. The physical card address is critical
and should match the value configured for the device number
(DNUM) in LD 17. Use LD 22 to obtain a printout of the ADAN
information.
The location of the switches is shown in Figure 40. The device
number should match the value configured in LD 17 (DNUM
prompt). See Chapter 12, ÒMeridian 1 configuration for
Meridian Link/CCRÓ for LD 17 configuration.
