I spotted this 6408D+ DCP telset at my last visit to the Attitash Grand Summit Resort in late October. This hotel off US302 is used mostly for conferences and skiers who want a vacation. This set was replaced in between a Labor Day week visit and the visit in late October. This area is a space for tourist information to help a customer find a place of interest. Previously (and years before) had a generic “trimline” like set. As previously posted, it appeared there was an upgrade of refurbished sets.
What would be nice given the decline of digital office telephony, that maybe digital sets could be seen in more locations in the facility or even in the rooms, despite Avaya and their BPs jacking up the maintenance costs of digital telephones in lieu of going to VOIP for no reason.
The 6400 series sets have been known unofficially to have a “European” look (but never claimed by Lucent or Avaya directly.) While Lucent introduced the line in the late 1990s, mass deployments occurred under Avaya tenure (spun-off late 2000.) The 6400 sets probably had a large friend count with the other models in the line. What do I mean? 6400 sets were often found in new deployments where a Definity or later MultiVantage systems would be setup. Because the 6400s were made around that time, other models like the 8400 was ether refurbished or not aggressively sold. It was not to say they couldn’t go in existing plants; just you’ll see them more obviously in new deployments after 2001.
These sets also introduced a mandatory two-wired setup (albeit with an RJ 45 jack) where a single pair of tip and ring would run on pins 4 & 5. Aux power would need two pairs with said T&R wire and another pair on pins 7 & 8 on an RJ 45 plug.
