My old antiquated crossbar central office is going equal access on December 11. At first, I thought this meant we were going to a #5 ESS or DMS-100 but no such luck. We're getting something called an adjunct frame, which basically allows a crossbar office to emulate the equal access aspect of an ESS office. Is anyone familiar with such setups? For example, I was told that these systems could not place 10XXX alternate carrier codes. However, since the system has started to be installed (over the past two days my dial tone has been accepting 1's which were never required before), I've noticed that I get different error messages if I dial 10288 or any other carrier code followed by a phone number than if I dial an invalid carrier code. So obviously, something is being cross checked. None of the phone calls go through (yet) using this method, however I've found that if I dial 10555, 10666, or almost any invalid carrier code, followed by 0, I'll get a New York Telephone operator, two 0's and I get an AT&T operator! Is this normal? I'd like suggestions as to other experiments I should be trying in this transitional period. And does anybody know if adjunct frames are REQUIRED to provide 10XXX service? I've also noticed that invalid exchanges that used to give me an error after 3d are now waiting for the full 7d. Eric Corley ecorley@dasys1.UUCP phri!dasys1!2600@nyu
