The customer is a Tier 1 Network Equipment Manufacturer (NEM) that is a world leader in packet-optical switches, optical transport solutions, and SDN networking software.
To provide a continuity of support for TDM circuit emulation, a new module for the multiport T1/E1 module was required. This new module would replace an older version. Overall the module needed to meet the following objectives:
- Lower the cost of goods (components).
- At a minimum, provide the same functionality & meet the same standards as the previous version.
- Be 100% plug & play compatible with the product chassis and platform.
- To add integrated APIs in order to enable network management support for this module.
AimValley was engaged to design a field replaceable unit with 16x T1/E1 ports, including the building of prototypes and providing system verification and test.
AimValley also provided one of its software products, called “Titan” which provides software control of the module/ports through a common API.
One key aspect of the design was to ensure that synchronization, timing, re-timing, and loop timing was provided through Digital Clock Recovery (DCR) and Analog Clock Recovery (ACR)
