Carrier Access Corporation’s Wide Bank 28 DS3 Multiplexer provides a standards-based M13 multiplexing function with TL1 management. This product converts a framed Digital Signal Level 3 (DS3) network connection into 28 Digital Signal Level 1 (DS1) connections to T1 facilities, or into 21 connections to E1 facilities. Each Wide Bank 28 DS3 can be equipped with DS1 cards or E1 cards, but not both. Independent Framing and Clocking The Wide Bank 28 DS3 does not re-frame or re-clock the low-speed inputs. It allows T1 or E1 framing to be provided independently by the connected communications equipment at both the near-end and the farend of the DS3 line. Each T1 or E1 is also independently clocked within the M13 formatted DS3 composite. Because of the independent clocking and framing capabilities for each of the T1 or E1 connections, the Wide Bank 28 DS3 can provide asynchronous T1 or E1 to DS3 multiplexing functions. Capacity and Protection The Wide Bank 28 DS3 unit’s modular design provides up to seven active quad DS1 (QDSX) cards or seven active triple-port E1 cards. One spare circuit card (DS1 or E1) provides software-controlled protection of low-speed interfaces on a 1 to 7 basis. The DS3 Controller card provides all common electronic functions of power conversion, processing and management, and a single DS3 interface. An optional redundant DS3 Controller card provides protection for both electronic common equipment and a second DS3 interface for network protection.
