Functional Description

Two ESCIU Outputs (990-72060-04 Systems Only)

This option provides a module for two E1 ports. The module mounts in the
OPTIONS I/O mountings on the connector panel. E1 traffic-carrying signals are
synchronized using the Bestime ensemble timing generator. Jitter and wander are
also removed before sending the E1 signals to network elements.
If an alarm condition or power failure occurs, relays allow the E1 signals to bypass
the system. (See Figure 1-8).

Alarm Interface
The microprocessor delivers alarms to normally open dry-contact type connections.
Alarms are also indicated by the front-panel status lamps.
Communication Ports
Three serial communication ports carry TL1 commands, responses, and
autonomous messages between the TimeSource 3600 and an external terminal.
Ethernet
TimeSource 3600 has six Ethernet ports to carry TL1 commands, responses, and
autonomous messages between the TimeSource 3600 and an external terminal, or
an Element Manager, or both. The user can configure the IP address, subnet mask,
and gateway address for the Ethernet ports.
Four ports (5001, 5002, 5003, and 5004) are configured to act as though a
serial-port communication terminal were connected to them. These ports
communicate TL1 commands, responses and autonomous messages.
