Clock Sources:

Internal, free-running oscillator. Phase-locked to any appropriate network interface. External input at T1 or E1 rate.

Clock Output:

Single clock output at T1 or E1 rate for synchronizing co-located IPX node(s) or CPE.

Clocking Hierarchy:

Network-wide or domain-wide (for structured networks) clock selection.

NMS Terminal:

Control Terminal:

DEC VT100 or equivalent terminal for basic system configuring and alarm monitoring.

Remote Alarm Reporting:

Autodial modem may be connected to one of two control ports on each node for automatic reporting of network alarms.

Remote Diagnostics:

Autoanswer modem may be connected to one of two control ports on each node for remote diagnostic access by StrataCom ISC or other authorized personnel.

Network Control Ports:

Three ports per node, two with RS 232C interface, one with Ethernet LAN interface. (Nodes with PCC controller have only the two RS-232 ports).

Alarm Notification:

Status of all trunks and nodes in network distributed to and stored by each individual node. Reported to StrataView Plus terminal at connecting node.

External Alarms:
