Chassis

Figure 1-2 shows the front panel of the Cisco IAD1101 chassis.

Figure 1-2: Cisco IAD1101 Front Panel

Table 1-1 describes the LEDs on the front panel.

Table 1-1: Front Panel LED Indicators

LED	Status	Condition
POWER	Green Off	Cisco IAD1101 is on. Cisco IAD1101 is off.
SYNC	Green Off	Cisco IAD1101 is synchronized with an external timing source. Cisco IAD1101 is not synchronized.
ACTIVE	Green Off	Cisco IAD1101 is operational or performing a software upgrade. Cisco IAD1101 is powered off or initializing system software.

Figure 1-3 shows the rear panel of the Cisco IAD1101 chassis.

Figure 1-3: Cisco IAD1101 Rear Panel

The rear panel contains the following connectors:

Expansion slot for line interface module (FXS/16)
50-pin subscriber connector for up to 24 FXS circuits (16 onboard, 8 expansion)
V.35: 26-pin serial interface
ETHERNET: 10Base-T Ethernet interface (RJ-45)
CONSOLE: EIA/TIA-232 (RJ-45) console port for local access using an EMS workstation

Note The console port does not support a terminal connection.

T1-FAC2 and T1-FAC1: T1 interfaces (RJ-48)
BATTERY: Battery backup connector
GROUND: Ground connector
Power switch and AC power cord connector

Figure 1-4 shows the connectors and LEDs on the left side of the rear panel, and Table 1-2 describes the LEDs.

LED	Status	Condition
LINE 2	Green Yellow Red Off	T1 line is framed and in service. T1 port is experiencing far end failure. T1 port is experiencing loss of signal (LOS), loss of frame (LOF), or hardware failure. T1 port is out of service
LINE 1	Green Yellow Red Off	T1 line is framed and in service. T1 port is experiencing far end failure. T1 port is experiencing loss of signal (LOS), loss of frame (LOF), or hardware failure. T1 port is out of service
VBAT	Green Off	Battery is supplying power to the Cisco IAD1101. Battery is not connected or not supplying power.

FXS Circuits

The Cisco IAD1101 provides 16 FXS circuits with ring generation and line test functionality. These FXS circuits support loop start and ground start operation, with full-time on hook transmission.

For FXS circuit specifications, see the "FXS/16" section.

T1 Ports

The two T1 ports on the Cisco IAD1101 can be provisioned for T1 (long haul) or DSX1(short haul) signaling and line buildouts.

Bandwidth: 1.544 Mb/s
Frame format: ESF, SF
DS0 mapping: D4
Line coding: AMI, B8ZS

Line interface modules for the Cisco IAD1101 integrated access device are hot swappable. They can be inserted into (or removed from) the Cisco IAD1101 module slot with or without power applied to the system without incurring damage.

The following line interface modules are available for the Cisco IAD1101:

FXS/16

FXS/16

Each FXS/16 line interface module provides 16 circuits of FXS service.

Note Only 8 POTS/FXS circuits on the FXS/16 module are supported in a Cisco IAD1101 chassis, giving a total of 24 POTS/FXS circuits—16 internal circuits, and 8 on the FXS/16 module.

LEDs

The LEDs on the FXS/16 module indicate module status. (See Table 1-4.)

Table 1-4: FXS/16 LED Indicators

LED

Status

Condition

FAIL

Red

Off

FXS/16 module has failed.

FXS/16 module has not failed.

BUSY

Green

Off

FXS/16 module is in service, and at least one port is in service.

FXS/16 module in not in service, or no ports are in service.

Alternately blinking FAIL and BUSY LEDs indicate that a slot has been provisioned in EMS for another type of module.

Connectors

Use the 50-pin analog subscriber connector to connect the FXS/16 module. See "Connector and Cable Specifications," for connector information.
