Off-Campus and Collect Calls

Off-campus calls are made by using a Personal Security Code (PSC) provided by AT&T ACUS Service. Your PSC is a campus calling card that allows calls to be billed to you when you enter your private code. Your AT&T ACUS account and PSC will be sent to your home address prior to your August arrival or can be picked up at the Office of Communications Services in 102 Philosophy. To make off-campus calls from any Rolm station, dial 97, followed by your PSC and the number. To dial toll-free area codes (e.g., 800), dial 96 + 1 + area code + number.

You will receive an email around the 5th of each month notifying you that your bill is ready for viewing. If you prefer, you may arrange to receive your invoice via campus mail for $1.50 per month. It is your responsibility to notify AT&T ACUS of any changes to your email, home, campus address, or phone number. Go to www.acus.com using your 10-digit account number and 10-digit PSC. You may also call them at 1-800-445-6063.

There is a service charge for receiving collect calls and all other manually billed calls. Roommates using a common line will share the bill if it cannot be determined which party is responsible.

Troubleshooting

• Make sure your phone is plugged into the “voice” side of the two-sided or four-sided voice/data jack. If there happens to be a standard telephone jack in your room, do not use it.

• Try connecting another phone to the jack in question. If this phone also fails to produce a dial tone, the jack is most likely in need of repair. If the second phone works properly, the problem is most likely with your current phone.
  
  
• Try replacing the wall cord from your nonworking phone with the wall cord from a functioning phone. If the phone still does not work, try replacing the receiver cord.
  
  
• If your phone, phone-jack or phone-receiver cord is broken, you may obtain another one at the CUIT Client Service Center in 102 Philosophy Hall.
