information
Provided the functional guidelines described in this chapter are followed, the
steps involved in upgrading an existing site with mixed equipment are
essentially the same as with a conventional upgrade:
 Determine the number of additional carriers required in the upgraded site.
 Based on the required site configuration (for example, 4/4/4), use the
functional guidelines provided in this chapter to decide the most effective
hardware configuration for the additional cabinet(s).
 Special upgrade kits are available for specified configurations.
 Configuration diagrams and product ordering help are available from the
Motorola local office.
