The Norstar DID trunk card provides Disconnect Supervision and access for up to four (4) CO lines. DID trunks do not support CMS/CLASS services.
The Norstar DID trunk card works with the Modular 8x24 and Modular ICS (MICS) phone systems. Requires one slot in a copper or fiber trunk module. This card does NOT work on the Norstar 3x8 or Compact ICS (CICS) phone system.
