As CMC Telecom rapidly expands to meet the local communications needs of businesses like yours, we offer a full range of advanced services, including state of the art Local Trunk Service. For companies with a PBX or key system, our Local Trunk Service provides both digital and analog capabilities to meet your business needs.

Local Trunks are basic communication circuits between the local end office switching center and your PBX or hybrid system (a hybrid system combines both Key System and PBX capabilities). CMC Telecom Local Trunks offer three service options:

Local Trunk Basic
Provides a single digital or analog connection that can carry inbound, outbound or two-way traffic.

Local Trunk Direct Inward Dialing (DID) for digital trunks only

Provides a digital connection that carries inbound traffic only. This option is configured to out-pulse 2-7 digits to your CPE (customer premise equipment), allowing flexibility for your internal extension plan. The digits received allow your CPE to route an incoming call directly to an individual station without the intervention of a live or automated attendant.

Local Trunk Two-Way Direct Inward Dialing for digital trunks only
Provides DID capability with the added function of allowing the ability to place outbound calls on the same trunks.

CMC Telecom offers both Analog and Digital Trunks

Analog Trunks
Analog Trunks are used to provide non-digital connectivity from the Local End office to your PBX. CMC Telecom Analog Trunks may be provisioned as: one-way in, one-way out, or two-way.

Digital Trunks
Digital Trunks are used to provide digital connectivity from the Local End office to your PBX. A T1 (1.544 mbps) channel is provided and multiplexed into channel banks for Analog PBXs. Digital PBXs are T1 ready with cards. CMC Telecom Digital Trunks may be provisioned in one of many ways: one-way in, one-way out, or two-way.

Local Trunks are ideal for:
  • Medium - Large Size Businesses
  • Customers requiring the features and functionality of a PBX phone system.
