Control leads are sampled every 50 ms. A change normally follows data within 100 to 1000 msec. Fast EIA lead is within 1 byte.

Data clocking:

Synchronous and isochronous clocking.
Normal, looped, and split clock configurations.

Pleisochronous
clock range:

± 2 percent of nominal data rate.

Type of Service:

Permanent Virtual Circuit (PVC).

Interface Types:

User-to-Network (UNI) and Network-to-Network (NNI) per ITU-T I.361 and I.363.

Data Rates:

T1, E1, T3, E3, OC3 (STM-1).

ATM Layer:

Physical Layer Convergence Protocol per AT&T publication TA-TSY-00772 and 000773 for T3; ITU I-361 with HEC for E3.

Cell Rate:

T3: 96,000 cps in PLCP mode, 104268 cps in HEC mode.

E3: 80,000 cps.

Adaptation Layer:

AAL5.

Number of PVCs per card:

255.

VPI Addressing Range:

0-255.

VCI Addressing Range:

0-65535.

Traffic Queues:

CBR, VBR, and ABR (except ALM/A).

Management Protocol:

LMI (Layer Management Interface) and ILMI (Interim Layer Management Interface).

External Clock Sources:

The IGX switch synchronizes to the nearest, highest-stratm clock available. Any T1, E1, T3, E3, OC3 (STM-1) line, trunk, or optional external clock input can serve a clock source.

Internal to Node Source:

T1: 1.544 MHz, ± 10 ppm. (stratm 4).
E1: 2.048 MHz, ± 10 ppm (stratm 4).

Clocking Hierarchy:

Dynamic primary, secondary, and tertiary clocking.

Network Control Terminal:

Cisco WAN Manager workstation and Cisco software required for graphical display of network status, statistics gathering and display, and automatic downloading of software.

Control Terminal:

DEC VT100, WYSE 85, Televideo 970 or equivalent terminal for basic system configuring and alarm monitoring.

Remote Alarm Reporting:

Auto-dial modem connects to one of two control ports on each IGX node for automatic reporting of network alarms.

Remote Diagnostics:

Auto-answer modem connects to one of two control ports on each IGX node for remote diagnostic access by Cisco TAC or other authorized personnel.

Network Control Ports:

Two ports per node—one EIA/TIA 232C interface and one Ethernet LAN port.

Alarm Notification:

Status of all trunks and nodes in network distributed to and stored by each individual node. Reported to Cisco WAN Manager workstation at connecting node.

External Alarms:

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

Indicators and Controls:

Active and Fail lights on all cards and power supplies.
