Line Receive Synchronous 28:1. Multifunction input.
Channel assignment may be configured through the
internal cross connect. Can be used as the negative rail
of a DS1/E1 signal in conjunction with LINERX-
DATA(28:1), when operating in dual-rail mode. In CHI
mode these inputs are used for receive TDM highways
that may run at 2.048, 4.096, or 8.192 Mbits/s. In paral-
lel system bus mode the receive system data bus inputs
are assigned to LINERXSYNC 16:1. The PSB is a 16-
bit wide bus that operates at 19.44 MHz.
Line Receive Synchronous 29. Multifunction input.
Channel assignment may be configured through the
internal cross connect. Can be used as the negative rail
of a DS1/E1 signal in conjunction with LINERXDATA 29,
when operating in dual-rail mode.
In CHI and PSB modes this input is used as the receive
system frame synchronization input. In NSMI mode, it is
the receive frame sync output
Line Transmit Data (28:1) Configurable outputs from
the internal cross connect. Used for transmit positive-
rail or single-rail DS1/E1 line data outputs. May be con-
nected to the DS1/E1 outputs from the VT mapper, M13
MUX or DS1/E1 frame line outputs. May also be used
as a DS2 output.
Line Transmit Data 29. Configurable output from the
internal cross connect. An extra DS1 or E1 transmit port
that may be used for protection or as a timing reference
output.
