I
TDCS6440G will interface seamlessly to a number of Lucent Microelectronics existing/next-generation high-
speed framers.
Description
The TDCS6440G has four sections: receive interface channels, a cross connect fabric core, transmit channels,
and a microprocessor interface. The block diagram of the TDCS6440G is shown in Figure 1.
All data stream channels must be synchronous in frequency, but can be asynchronous in phase.
The TDCS6440G does not perform pointer processing functions. These are performed by the line and tributary
cards, which align the payload at known positions relative to a common frame signal.
The TDCS6440G is able to support SONET and SDH cross connects.
The A1, A2, B1, H1, H2, H3, K1, and K2 bytes are used for their original SONET/SDH purposes.
Note:
Throughout this document, the term channel always refers to an STS-12 data stream that is carried on a sin-
gle LVDS link.
