Vanguard Managed Solutions 3400 Series ユーザーズマニュアル

B-2 

Before a Vanguard 3400 Series can be connected to the network, you must do the 

following:

• Provide the local telephone company with the equipment’s registration num-

ber.

• Order the proper connections 

To order the proper connections, provide the telephone company with the following 

information:

• Interface type
• Required USOC jack connector number 
• Service code
• Facility interface codes

If any of your equipment is not operating correctly, immediately remove it from the 

telephone line before damaging the network. If the telephone company is aware of 

the problem, they may temporarily disconnect your service. Whenever possible, the 

telephone company notifies you in advance of the disconnection.
If advance notice is not feasible, you are notified as soon as possible. Once notified, 

you can correct the problem. If necessary, it is your right to file a complaint with the 

FCC.
