Assignee:

Pulse Communications, Inc. - Herndon VA

International Classification:

H04J 3/04

US Classification:

370532, 370540

Abstract:

An integrated digital loop carrier (IDLC) system includes digital line feeders and signal processors to interface with the feeders an to ultimately provide data to subscriber instruments. The system can be employed as a central office terminal (COT) or remote digital terminal (RDT) with analog, T1 or SONET feeders and any conventional link medium. Data are put in DS1 format and multiplexed onto token ring optical loops for delivery to banks of channel units wherein the optical signals are translated to electrical signals for delivery to the Cus and subscribers. A method and apparatus is provided for mapping and demapping signals between virtual tributaries (VT) and digital signal formats in the RDT of an integrated digital loop carrier. An application-specific circuit provides such mapping and demapping functions as Floating Byte Synchronous VT to Locked Byte Synchronous VT, Floating Asynchronous VT to Locked Byte Synchronous VT, Floating Asynchronous VT to Floating Asynchronous VT, DS1 to Locked Byte Synchronous VT, DS1 to Floating Asynchronous VT, and DS1 to Floating Byte Synchronous VT.

International Classification:

G06F 700

US Classification:

370249

Abstract:

A control system for a network element (NE) such as a remote digital terminal (RDT) in an integrated digital loop carrier (DLC) system is provided which comprises subsystems for operating circuit packs and for providing functions that are common to the circuit packs. Each subsystem has a subagent residing on a network processor circuit pack. The subagents communicate via a common subagent interface. A NE which supports both OSI and non-OSI interfaces such as Transaction Language 1 (TL1) and Common Management Services Element (CMISE) interfaces is provided, along with a method for mapping TL1 commands to CMISE messages using TL1 proxy objects.
