omnitron 4 Port T1/E1 MUX Managed Ethernet

Product Overview

The 4 Port T1/E1 MUX modules support four copper RJ-48C ports for balanced T1/E1 applications and 4 E1 coax ports when used with external cabling. Model 8486- 4 features an external clock port that can be configured as a clock input or output. This User Manual is for product revision xx/20.
NOTE: All modules in the T1/E1 MUX grouping must be at the same firmware release to ensure proper operation and the fiber transport module should be at firmware release 4.2 or greater.
See full user manual for more detailed information. Registration is required.

DIP-Switches

DIP-Switch Bank 1

DIP-switches are located on the side of each T1/E1 MUX module. The DIP- switches are used to configure line codes, line build-out and different loopback and test conditions.
See the complete User Manual for detailed information on the loopback, test functions and management support

The location of the DIP-switches is shown in Figure

1. The functions of DIP-switch Bank 1 are outlined in Figure 2.

SW1 – SW4: Local Loopback Port 1 – Port 4
When these DIP-switches are in the “On” position, the corresponding port initiates a local copper loopback. An AIS (all 1s signal) from the local port is transmitted across the fiber and out the corresponding T1/E1 port on the remote unit. When these DIP-switches are in the “Off” (default) position, the port functions normally. See the Modular T1/E1 Multiplexer User Manual for more information.

SW7
SW8

SW5 – SW8: T1/E1 Line Configuration Settings
These DIP-switches configure the T1/E1 MUX modules for T1/E1 operation and the copper line build-out.

DIP-Switch Bank 2

The functions of DIP-switch Bank 2 are outlined in Figure 4.

SW1 – SW4: Port Alarm Relay/LED
These DIP-switches enable/disable the port alarm relay and LED functions for the corresponding port on the T1/ E1 MUX module as shown in Figure 4. When these DIP-switches are in the “Off” position (default), the alarm relay and Link “Lnk” and Remote “Rmt” LEDs are enabled. When these DIP-switches are in the “On” position, the alarm relay, “Lnk” and “Rmt” LEDs are disabled.
Port Alarm Relay:
The port alarm relay will close when any of the following port alarm conditions are detected (i.e. alarm relay port 1 will activate when an alarm condition is detected on port 1).

• Power loss
• The detection of AIS or Loss of Signal (LoS) on any of the four local T1/E1 copper ports
• The detection of AIS or LoS on any of the four remote T1/E1 copper ports
• When the T1/E1 MUX is not peered with its remote partner

NOTE: The alarm relay uses pins 7 & 8 of port 1 on each T1/E1 MUX module. If more than one T1/E1 MUX module is installed, each alarm relay operates independently from the other modules. Use the optional breakout cable to access the alarm relay pins: part number 9142-1.

SW5: Circuit Test (C/T) Mode
When this DIP-switch is in the “Off” position (default), the Circuit Test Mode is disabled. When this DIP switch is in the “On” position, the Circuit Test Mode is enabled. Circuit Test Mode only needs to be enabled on one end for the test to initiate.
When Circuit Test mode is enabled, both T1/E1 MUX modules will transmit a known test pattern. The test pattern is received by the other unit and checked for errors. AIS is transmitted out all T1/E1 ports and incoming T1/E1 traffic is discarded. A solid green “Stat” LED indicates a successful test. See the Modular T1/ E1 Multiplexer User Manual for more information and description of each LED.

SW6: Local Fiber Loopback
When this DIP-switch is in the “Off” position (default), local fiber loopback is disabled. When this DIP-switch is in the “On” position, local fiber loopback is enabled on the MUX module. AIS is transmitted across the fiber and out all remote T1/E1 ports. Incoming T1/E1 traffic at the remote unit is discarded. See the Modular T1/E1 Multiplexer User Manual for more information.
NOTE: Only one loopback activation (Local Fiber Loopback or Remote Fiber Loopback) can be configured at the same time.

SW7: Remote Fiber Loopback
When this DIP-switch is in the “Off” position (default), remote fiber loopback is disabled. When this DIP-switch is in the “On” position, remote fiber loopback is enabled on the T1/E1 MUX module. In this mode, the local unit forces the remote T1/E1 MUX module into loopback. AIS is transmitted out all remote T1/E1 ports. Incoming T1/E1 traffic at the remote unit is discarded. See the Modular T1/E1 Multiplexer User Manual for more information.
NOTE: Only one loopback activation (Local Fiber Loopback or Remote Fiber Loopback) can be configured at the same time.

SW8: T1/E1 Line Codes
When this DIP-switch is in the “B8ZS” position (default), the MUX module is configured for B8ZS (T1) or HDB3 (E1) line coding. When the DIP-switch is in the “AMI” position, the MUX module is configured for AMI line coding.

DIP-Switch Bank 3

The functions of DIP-switch Bank 3 are outlined in Figure 5.

SW1: Backplane Configuration
When this DIP-switch is in the Left “Auto” position (factory default), the Backplane Port of the T1/E1 MUX module automatically connects to adjacent T1/E1 MUX and TM3 modules creating a MUX group. When this DIP-switch is in the Right “Manual” position, the backplane port is forced on and Ethernet traffic is sent to and received from the backplane partner. When in “Auto” DIP- switches SW2 and SW3 are ignored. The recommended setting is “Auto”.

SW2 and SW3: Backplane
When these DIP-switches are in the Left “Disable” position and SW1 is set to “Manual”, the backplane is disabled. When these DIP-switches are in the Right ”Enable” position and SW1 is set to “Manual”, the backplane is enabled. When SW1 is set to “Auto”, SW2 and SW3 are ignored.

SW4: Payload Loopback Activation
When this DIP-switch is in the Left “Disable” position, the ports will not respond to FAC2 NIU2/NIU5 loop-up and loop-down codes. When this DIP-switch is in the Right “Activate” position, the ports will respond to FAC2 NIU2/ NIU5 loop-up and loop-down codes.

SW5: Remote Fiber Loopback Override
When this DIP-switch is in the Left “Enable” position, the module will respond to the remote loopback request (DIP-switch BANK 2 SW7) from the remote T1/E1 MUX. When this DIP-switch is in the Right “Disable”, the module will not respond to the remote loopback request.

SW6: Clock Timing Mode
When this DIP-switch is in the Left “Adaptive” position, the module is set to line or adaptive clock timing mode. Line or adaptive clock mode is configured through management using Secondary Clock Mode soft-switch. Adaptive clock mode should be used at the remote end where the T1/E1 equipment uses loop timing (recovered clock). Line clock mode should be used at the head end where the T1/E1 equipment is clocked by an accurate source (Stratum 3 or better). When this DIP-switch is in the Right “Internal” position, the module is set to internal clock using an onboard clock oscillator. See the Modular T1/E1 Multiplexer User Manual for more information.

SW7: Clock Termination (For Model 8486-4 Only)
When this DIP-switch is in the Left “No Term” position, the module does not terminate to the Coax Clock I/O connector. When this DIP-switch is in the Right “Term” position, the module terminates the Coax Clock I/O connector with a 50 ohm termination.

SW8: On-Board DIP-switch Control
When this DIP-switch is in the Left “Enable” position, DIPswitch BANK 1 and DIP-switch BANK 2 are enabled and can be modified. When this DIP-switch is in the Right “Disable” position, DIP-switch BANK 1 and DIP-switch BANK 2 are disabled and will not accept modifications.
Jumper JP4 (For Model 8486-4 Only)

When JP4 is in the “Closed” position, the Coax Clock I/O connector is an output and the signal is the recovered transmission clock from Port 1. When JP4 is in the “Open position, the Coax Clock I/O connector is an input and the module uses the incoming clock signal. The input clock must match one of the acceptable clock signals to be used by the module; 10MHz, 1.544MHz or 2.048MHz (TTL).

Mounting and Cable Attachment

A TM3 Transport module and up to four contiguous 4 Port T1/E1 MUX modules combine to form a MUX group. A MUX group can connect with another MUX group at the opposite end of a dedicated fiber link. A MUX group can also interoperate with a Managed iConverter fixedconfiguration T1/E1 Multiplexer. Multiple MUX groups can be installed in a chassis, enabling high-density, star-topology deployments.
Caution: Use proper ESD protection to reduce the risk of damage to your equipment.

• a) Carefully slide the module into an open slot in the chassis. Align the module with the installation guides and ensure that the module is firmly seated against the backplane. Secure the module by fastening the front panel thumbscrew (push in and turn clockwise to tighten) to the chassis front. Verify the “Pwr” LED is ON (indicating the chassis is powered).
• b) The T1/E1 MUX modules must be installed in adjacent slots to the TM3 Transport module. The slot numbers must be greater then the slot number of the TM3 Transport module. Up to four T1/E1 MUX modules can be installed in adjacent slots.

• c) Connect a Category 3 or better cable (Category 5 is recommended) to the RJ-48C connectors on the T1/E1 MUX module, and attach the other end of the UTP cable to the network equipment. The pinout for the RJ-48C is shown in Figure 8.
  NOTE: For some installations, a crossover cable may be required (Pin 1 to Pin 4, Pin 2 to Pin 5).
  d) When configured for E1 coax operation, use the optional adapter cables to convert the RJ-48C interface ports to dual BNC (part number 9140-3) and set the T1/ E1 Line Configuration DIP-switch for E1 75 W Coax.
  e) For Model 8486-4 only. Connect a coax cable with a female SMB connector to the Coax Clock I/O connector on the T1/E1 MUX module. Termination of the clock will be required via DIP-switch SW7 (23) or external termination using a “T” connector. To daisy chain multiple clock inputs, use a female BNC T connector. Only one termination on the cable is required at the end of the chain.
