CTP2008 Circuit to Packet Platform is a 1 U rack-mountable chassis that supports up to 8 circuit emulation interfaces. The interface modules are software configurable and are the same across the CTP2000 line. Interface options include T1/E1, serial, and 4WTO analog voice. CTP Series Circuit to Packet Platforms have the field-proven flexibility, performance, and reliability required for circuit applications, including advanced clocking options and per-circuit buffers that enable end-to-end timing and jitter removal to create a pseudowire across the IP/MPLS network.
