Meridian America Link/Customer Controlled Routing manual Installing an Esdi or Msdl card

Chapter 8: Hardware installation procedures 145

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.

1Unpack and inspect the card.

2ESDI card onlyÑset the faceplate switch to DIS.

3ESDI 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.

4MSDL 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.
