308 Using COS passwords
N0008589 3.3
COS examples
Example: Using the COS feature to access a restricted line
A sales representative out of the office needs to make long distance calls to the European office.
Your system has a leased line to Europe with reduced transatlantic charges. You provide the sales
representative with a Class of Service password that gives access to the transatlantic line. The sales
representative can telephone into the system (DISA DN) from a hotel, enter the Class of Service
password, and then use a destination code to access the leased transatlantic line to make calls.
To bypass the restriction filters on a line or telephone:
1 Press FEATURE 68 .
2
Enter the six-digit COS password that allows the required type of call.
3 Enter the number to be dialed.
Example: Remote access over the public network
Follow this procedure to access the system over a public network.
1 Dial the system remote access number.
2
When you hear a stuttered dial tone, enter your COS password.
3 Wait for the system dial tone.
To use the system at a distance, you must use a telephone with tone dialing to call the system.
Remote access is possible only on lines that your installer programs to auto-answer calls.
To use features on a remote system, press * followed by the feature code. When you are calling
from within Business Communications Manager, press * instead of FEATURE .
In some conditions, you can experience lower volume levels when using the system from a
distance.
