Network Working Group R. Alter Request for Comments # 356 Bolt Beranek and Newman Inc. NIC # 10598 June 21, 1972 Categories: Updates: Obsoletes:

ARPA NETWORK CONTROL CENTER

1. Schedule -------- The NCC operations staff has recently been augmented so that the NCC is now manned 24 hours per day, 7 days per week. Please be sure to contact the NCC in case of any IMP/TIP or Network problems, at any time of the day or night.

2. NCC Phone Number ---------------- In the past we have been informed that persons trying to reach the NCC have occasionally received busy signals. In an effort to change that, we have installed a new set of phone numbers for the NCC. The new phone number for the Network Control Center is (617) 661-0100. Please post this new phone number prominently near IMPs and inform all concerned parties of this new phone number. (The old phone number will also continue to operate, for a while.)

Hereafter, if you receive a busy signal (please distinguish from the "fast busy signal", meaning "busy circuits"), then please persist, but also please be sure to inform the operator when you do reach him of the the fact that you received a busy signal.

3. Mail to the NCC should be addressed to: --------------------------------------

ARPA Network Control Center c/o Bolt Beranek and Newman Inc. 50 Moulton Street Cambridge, Massachusetts 02138
