Network Clock:

One clock source per domain must be defined. Network clock cannot propagate across domain boundary.

Node Clock:

44.736 MHz, ±50 Hz (Stratum 3 per AT&T Pub 62411). Internal
8 KHz and 192 KHz clocks for synchronizing network interfaces.

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:

SUN Microsystems and Cisco WAN Manager, Informix, Wingz, and HP OpenView software required for network management, connection provisioning, graphical display of network status, statistics gathering and display, automatic downloading of switch software, and save and restore of node configurations.

Control Terminal:

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

Remote Alarm Reporting:

Autodial modem may be connected to the auxiliary port on one or more IPX or IGX nodes for automatic reporting of network alarms.

Remote Diagnostics:

Autoanswer modem may be connected to the control port one or more IPX, IGX, or BPX nodes for remote diagnostic access by Cisco Customer Service 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 Cisco WAN Manager terminal at connecting node.

External Alarms:

Meets Bellcore Compatibility Bulletin #143 and AT&T Technical Reference PUB 43801 DS1 (T1) facility alarm requirements.
