Maintenance and administration terminals

Refer to “Terminal setup” on page 201 for information about setting up terminals recommended for use with the Option 11C Mini system.

Under some conditions, you require a Modem Eliminator (NULL Modem without hardware handshaking) A0601397 F-F converter or A0601396 M-F to interface the TTY to the system.

The following describes the minimum requirements for a TTY device:

Without Meridian Mail

When the system does not have Meridian Mail installed, and it will not have Meridian Mail installed in the future, the minimum requirement is a VT100 compatible device.

With Meridian Mail

With Meridian Mail installed, use a VT220 compatible device.

On-site access

Equip each system with an M2616 or M2008 telephone with display. These telephones act as maintenance telephones.

You can use many different TTY terminals to access the Option 11C Mini. However, a VT220 terminal is recommended as an on-site terminal. You can use this terminal to perform service changes, maintenance and diagnostic functions, and Meridian Mail administration activities.

Remote access

Although you can use several types of modems to access the system, a 2400 baud auto-answer modem is the recommended modem. A 1200 baud modem is the minimum requirement. You can use the modem to perform service changes, maintenance and diagnostic functions, and Meridian Mail administration activities from a remote location.

Note: You can perform additional maintenance functions through remote access on the Option 11C Mini. For additional information, refer to the Customer Configuration Backup and Restore Guide (553-3011-330).
