22 Cross Connect (XC) Block Functional Description (continued)
The path designations assigned to the framer are consistent with established network definitions. Signals multi-
plexed up into the digital hierarchy form the transmit path. Signals demultiplexed from the digital hierarchy com-
prise the receive path.
In switching applications, concentration highway interface (CHI) or parallel system bus (PSB) signals will enter
through the external I/O and are cross connected to the receive system interface (top right side of Figure 83). The
signals will traverse the framer through the transmit path frame formatter and are cross connected to the internal
multiplexers/mappers (top left side of Figure 83). Signals demultiplexed from DS3 or demapped from SONET are
cross connected to the receive path frame aligner (bottom left side of Figure 83) traverse the framer , and are cross
connected from the transmit system interface to the external I/O pins (bottom right side of Figure 83).
In transport mode, line interface (LIU) signals will enter through the external I/O and are cross connected to the
transmit path frame aligner interface (top right side of Figure 83). The signals will traverse the framer through the
transmit path frame formatter and are cross connected to the internal multiplexers/mappers (top left side of
Figure 83). Signals demultiplexed from DS3 or demapped from SONET are cross connected to the receive path
frame aligner (bottom left side of Figure 83), traverse the framer, and are cross connected from the receive path
frame formatter to the external I/O pins (bottom right side of Figure 83) on to the LIUs.
Most applications will cross connect the framer interfaces FRM_TP_T and FRM_RP_R to the M13 MUX or VT
mapper. The framer interfaces FRM_RP_T and FRM_TP_R or the system interfaces FRM_TS and FRM_RS will
be cross connected to the external I/O of the multifunction system interface.
22.3.2 External I/O to Cross Connect Overview
The cross connect defines the connectivity of device pins associated with the DS3 (6 pins), STS-1 POAC (6 pins),
and the multifunction system interface (174 pins). Therefore, the cross connect plays a very large role in configur-
ing the functionality of the Supermapper from the applications viewpoint.
The multifunction system interface device pin’s connectivity may be configured to support DS1/E1 (LIU and serial
data/clock/sync), DS2 interfaces, channelized (DS0), and multiplexed system interfaces (CHI, PSB, or NSMI).
