Chapter 3 Installing the TimeProvider

The TimeProvider has one Ethernet and two serial ports available. The Ethernet 
connector is on the front panel of the Front Access shelf and on the rear panel of the 
Rear Access shelf; the local Craft serial port is on the faceplate of the IMC or 
IMC/TPIU, and the Remote port is on the shelf. 

The local Craft serial port is used for control and monitoring of the unit, and is 
configured as a DCE device. The Remote port can be used for remote dial-in 
connection to the unit, and is configured as a DTE device.

Connecting to the Local Craft and Remote Serial Ports
To connect a device to the local Craft or the Remote serial port, perform the 
following steps:

1. Connect a 9-pin serial cable to the desired port.

2. Connect the other end of the cable to the serial port of the PC or terminal device. 

Use the procedure described in 

page 88, to connect to the TimeProvider.

The default settings for the local Craft serial port are DCE, 9600 Baud, 8 bits, no 
parity, 1 stop bit, echo on, and handshaking disabled.

The default settings for the Remote serial port are DTE, 9600 Baud, 8 bits, 1 stop

port settings revert to factory default values when you reset the IMC.
