SL-1 L, LE, and N system upgrades

Upgrading L, LE, and N systems to option 61C

Equipment required

This chapter covers these upgrades:
— SL-1 L, LE, or N system to Meridian 1 option 61C X11 release 21
To upgrade an SL-1 L, LE, or N system to an option 61C X11 release 21, you
must upgrade both the hardware and the software. Upgrading the hardware
consists of the following:
— removing the common equipment (CE) from the SL-1 cabinet
— installing a Meridian 1 option 61C column next to the SL-1 cabinet
— installing new connector housings on the SL-1 cabinet
— cabling the cabinet to the option 61C column
Upgrading the software consists of the following:
— if you choose to have the customer database converted, you must send it
to Northern Telecom for conversion; contact your Northern Telecom
representative to arrange for this. Alternatively, you can reenter the
database on the option 61C after the upgrade is complete.
Tables 3-1 and 3-2 list the items required to upgrade an AC- or DC-powered
system to an X11 release 21 Meridian 1 option 61C. Some configurations
may require items not included in the tables. All required items must be
identified and on hand before the upgrade can start.
Letters at the end of a part number represent the minimum vintage equipment
that can be used in the upgrade; only equipment of that vintage or later can be
used. Refer to Product compatibility (553-3001-156) for equipment
compatibility information.
