The DMS-10 switch, originally manufactured by Northern Telecom/Nortel Networks, is composed of three basic types of hardware: bays, shelves, and circuit packs. This hardware is assembled into various types of equipment. These different equipment types are then arranged to produce different DMS-10 system configurations.

ZT Technology Solutions can provide maintenance, provisioning, and troubleshooting or recovery of a DMS-10 system, no matter what the configuration.

No DMS-10 is too old for support by ZT Technology’s personnel. The span of the staff’s experience spans from the early days and introduction of the 200 generic switches, up to the 600 generic switches. Also, do you have a 1-bay or 2-bay system in a remote location? ZT personnel also have the knowledge base for that.

ZT can provide around-the-clock support for your DMS-10 needs.
