Signal Connections
Figure 2-19. Output Connections for T1 and Expansion Versions of I/O Module
E1 Connections
Two of the four coaxial ports on the 090-50311-01 and 090-50312-01, and
090-50315-01 versions of the I/O module (see
Figure 2-18 and Figure 2-19 ) are
software configurable as either E1 input or output ports. These ports are mini-BNC
male ports, except for the 090-50315-01, which uses SMB male connectors. They
can provide or receive the following signal types:

2.048 Mb/s (G.703/9)

2.048 MHz (G.703/13)
The 090-50311-01 version of the I/O module ( Figure 2-18 ) also has two mini-BNC
male ports that are dedicated E1 output ports with the following signal types:

2.048 Mb/s (G.703/9)

2.048 MHz (G.703/13)
T1 Connections
The 090-50314-01 version of the I/O module has two RJ-45 ports that are software
configurable as either T1 input or output ports (see
Figure 2-19 ). They can provide
or receive the following signal types:

1.544 Mb/s (G.703)

1.544 MHz (G.703)
Note:
Amphenol mini-BNC connectors (031-70261) can be
used to create cables. Alternatively, Symmetricom sells a kit of
4 mini-BNC to BNC adapter cables (093-00068-000).
Note: The T1 ports on t
he 090-50314-01 version of the I/O
module
can also be configured as E1 and 2048 kHz inputs or outputs
which meet the G.703 mask for impedance of 120 ohms, balanced.
