C4TEF10xx-11x
Slide-in-Module Device
• Twisted-Pair Copper to Fiber
• 10/100Base-TX to 100Base-FX
• RS-232 to Fiber
• (4) T1/E1 to Fiber
The C4TEF10xx-11x Device is designed
to install into a Transition Networks
PointSystem™ chassis and can extend
signals from a 10Base-T
Ethernet/100Base-TX Fast Ethernet port,
an RS-232 data port, and up to four (4)
T1/E1 network ports over fiber. The Ethernet, RS-232, and T1/E1 interfaces are
independent of each other and the signals from these ports can be sent over the
fiber interface simultaneously.
The C4TEF10xx-11x is designed to be installed in pairs. For example, install one
C4TEF1011-110 as the local Device and another C4TEF1011-110 as the remote
Device.
All C4TEF10xx-11x models have the following copper connectors:
The various fiber connectors are available on separate models. Both duplex and
single mode fiber opticDevices are available:

5, 6, 7, 8 - Loop-Back settings
The loop-back setting is used for installation and network debugging procedures.
Each of the T1/E1 ports can be individually set for loop-back mode:
• Switch 5 controls T1/E1 port 1
• Switch 6 controls T1/E1 port 2
• Switch 7 controls T1/E1 port 3
• Switch 8 controls T1/E1 port 4
When the loop-back switch for a particular T1/E1 port is enabled, the port loops
the signal from the receive port back to the transmit port. The T1/E1 loop-back
test scenarios are described in detail in under Troubleshooting.

Switch Set #2 - Serial and Ethernet Options
6 - Twisted-Pair Auto-Negotiation
up (Enabled) - The Device “advertises” ALL rate
and mode capabilities to the network:
• 100 Mb/s full- or half-duplex
• 10 Mb/s full- or half-duplex
The Device brings up the Ethernet link to the
highest speed and mode possible for all the
attached network devices.
When selected, Auto-Negotiation allows a twisted-pair link to become
operational only after the Auto-Negotiation function matches network speed
capabilities at both ends of the twisted-pair copper segment.
down (Disabled) - The bridging Device does not “advertise” the rate and mode
capabilities to the network. Switch 7 and switch 8 are then used to set the speed
and mode for the Ethernet link.
NOTE: Switch 7 and 8 are inactive if switch 6 is enabled (UP).
7 - Ethernet Speed
up (100Base-TX) - Sets the Ethernet port to
100Base-TX (100 Mb/s).
down (10Base-T) - Sets the Ethernet port to
10Base-T (10 Mb/s).
8 - Ethernet Mode
up (Full-Duplex) - Sets the Ethernet port to full-
duplex mode. The twisted-pair cable distances
are constrained by the cable requirements (see
Cable Specifications for the various C4TEF10xx11x models).
down (Half-Duplex) - Sets the Ethernet port to
half-duplex mode. The twisted-pair cable
distances are constrained by the 512-bit rule:
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain. (A collision
domain is the longest path between any two terminal devices, e.g. a terminal,
switch, or router.)
The 512-bit rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision domain.
If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-bit rule, see the white paper titled “Collision
Domains” on the Transition Networks website at: www.transition.com.

The loop-back setting is used for installation

from the receive ports back to the transmit
ports. The fiber loop-back test scenarios are

Switch Set #2 - Serial and Ethernet Options
9 - Transparent Link Pass-Through
up - Enable Link Pass-Through
down - Disable Link Pass-Through
The Transparent Link Pass-Through feature allows the Device to monitor the
Ethernet copper RX (receive) ports for loss of signal. For example, when the
Ethernet copper link on the near end device is lost (1), the local Device transmits
a signal to the remote Device (2), thus, “passing through” the link loss. The
remote Device disables the Ethernet copper link to the far-end device (3), which
prevents the loss of valuable data unknowingly transmitted over an invalid link.
It is important to remember that, although the Ethernet copper link has been
disabled, the fiber link is still valid (4). Thus, there is no disruption to the transfer
of T1/E1 or RS-232 data signals over the fiber link.
