2.3.1 TCC2P Functionality
The TCC2P card supports multichannel, high-level data link control (HDLC) processing for the DCC.
Up to 84 DCCs can be routed over the TCC2P card and up to 84 section DCCs can be terminated at the
TCC2P card (subject to the available optical digital communication channels). The TCC2P selects and
processes 84 DCCs to facilitate remote system management interfaces.
