Don,
Thanks for this information. The max equipment width of 21.25" is
what I was looking to verify and several sources are in agreement. Your
assistance is greatly appreciated.
Thx,
Joe

Importance: High
Joe and Ed,
I took careful measurements today. 23" is the distance between the
far ends of the mounting ears on the sides of the equipment. The
maximum width of the equipment itself is 21 1/4 inches. The center
of the mounting holes on one side to the center of the holes on the
other side is 22 1/4". The inside opening width is 21 1/2" and the
outside width measurement of the network rack is 26". The standard
heights for "23 inch" network equipment racks are 7 foot, 9 foot, and
11 foot 6 inches.
I hope this is somewhat helpful to you. I will continue to look for
appropriate documentation.
Don

Joe,
It is my belief that the 23" is the nominal distance for the mounting
hole spacing on the equipment "ears". The inside width of the
flanges being a minimum of 500mm and the outer width dimensions of
the flanges being 600 mm. The second set of requirements show the
inside and outside dimensions for a power lineup.
I have seven Zone 4 network relay racks at our museum from Newton,
AT&T and Hendry. They are all exactly the same with the same
measurements. These racks house a DDS STC Hub and End Office. The
equipment is designed to "just fit" into the racks. I will get out
my tape measure and send you what I find out. I will then try to
match the data with the proper specification. I am sorry I was not
more helpful the first time around.

Don,
I reviewed Section 3 previously and don't see where they address the
19" and 23" racks, only the "desired" NEBS 2000 Framework Criteria for 600mm
and 750mm racks. Am I missing something here?
R3-15 [57] The width of the flange aperture (the width of the open
space between the uprights) shall be 500 mm, +2 mm/-0 mm for the 600-mm wide
frameworks, or 650 mm, +2 mm/-0 mm wide for 750-mm wide frameworks.
500mm = 19.7" and 650mm = 25.6".
This is nowhere near the "equipment width" dimensions of 19" and 23"
C.O. equipment.
Thx,
Joe

Would anyone be able to provide the maximum width dimensions for
C.O. equipment destined for a 23" rack? I perused through GR-63 and only
found rack dimensions. A reference to the corresponding Telcordia spec
would helpful as well.
Thx,
Joe
