[comp.dcom.telecom] Pay Phones in National Airport

cmoore@brl.mil (VLD/VMB) (12/01/89)

In October, I visited National Airport and looked over the pay phones,
of various types.  (Area code 703, in an area still reachable via
202.)  Most were on 486, 684, 685.  I think I saw one phone on 548
(old-town Alexandria prefix), and I saw at least 4 AT&T
green-video-display-screen phones on 271 (a new prefix in Crystal City
area).

A 0+ call I made from 271 resulted in "703-271 Alexandria" on my phone
bill (Alexandria/Arlington is lumped together in the call guide, but I
consider it a bit of "noise" to display 271 as Alexandria; Crystal
City/Columbia Pike exchanges are, strictly speaking, Arlington).

Instruction cards have not changed, and 7D for ALL local calls is
still valid (this excludes extended-area calls to Prince William and
local calls from some Md. points to 301-569).  However, these phones
apparently already have the calling scheme described earlier in
Telecom (7D for local calls NOT crossing NPA line, NPA+7D for local
calls crossing NPA line, 1+NPA+7D elsewhere).  NPA+7D for local calls
NOT crossing NPA line is valid!  (does this simplify the programming
of the equipment?)  Lastly, 202+7D is valid only for calls to DC
proper.

(Just south of there, across 4 Mile Run, between the George Washington
Mem. Pkwy. and the Potomac, is an area which includes a marina, and
the pay phones there are all old-town Alexandria.)
