Cross-Connect Fields
Eac h Main Distrib ution Frame (MDF) c ontains a trunk/auxiliary field  and  a 
d istrib ution field . The trunk/auxiliary field  c ontains three c ross-c onnec t areas:
1.
The g reen field terminates the network interfac e leads from the Central 
Offic e (CO) and  p rovid es the terminals to c ross-c onnec t the leads to the 
p urp le or yellow field s as req uired . A sing le row of the 110-typ e terminal 
b loc k c an terminate twenty-four 1-p air, eig ht 3-p air, or twelve 2-p air 
trunks.
2.
The purple field terminates the trunk c irc uits from the system with 
WP-90929, List 1 or 3 c onc entrator c ab les. Also, 25-pair c ab les c an b e 
used  to terminate trunk c irc uits from the system with eac h trunk c irc uit 
p ac k c onnec ting  to one 25-p air row of the 110-typ e terminal b loc k. Eac h 
terminal b loc k row c an terminate twenty-four 1-p air, eight 3-p air, or twelve 
2-p air trunks.
3.
The yellow field p rovid es c ross-c onnec t terminals for all misc ellaneous 
lead s from the system, suc h as alarm monitors, emerg enc y transfer relay 
p ower, and  attend ant c onsole p ower. This field  is used  for emerg enc y 
transfer wiring , p ag ing eq uipment, music  sourc es, and  so forth.
The d istrib ution field  c ontains four c ross-c onnec t areas:
1.
The purple field (p ort field ) terminates 25-p air c ab les from the system. 
Eac h line c irc uit p ac k c onnec ts to one 25-p air row of the 110-typ e terminal 
b loc k. One 25-p air c ab le is required  for eac h line c irc uit p ac k.
NOTE:
The 16-port analog  line c irc uit p ac k req uires an ad ap ter c ab le to 
c onnec t from one c onnec tor on the system to two 25-pair c onnec tors 
on a terminal b loc k. Two MET c irc uit p ac ks req uire a c onc entrator 
c ab le to c onnec t from two c onnec tors on the system to one 25-p air 
c onnec tor on a terminal b loc k.
2.
The yellow field (auxiliary field ) terminates all 25-p air c ab les from the 
auxiliary c ab inet and the Proc essor Interfac e. The yellow field  is loc ated  in 
the lower rig ht-hand  c orner of the d istrib ution field.
3.
The white field (station field ) terminates the station wiring . The white field  
indicates 3-pair station circuits (eight circuits per 25-pair c able) routed 
throug h a satellite c loset.
4.
The blue field (station field ) also terminates station wiring . The b lue field  
indic ates 3- and /or 4-p air station c irc uits (six or eig ht c irc uits, resp ec tively, 
p er 25-p air c ab le). The fourth p air, of the 4-p air station c irc uit p rovid es 
ad junc t p ower from the c ross-c onnec t field  on an as-need ed  b asis to 
terminals within 250 feet (76 m) of the MDF.

Installation Requirements
Off-Premises Circuit Protection
Protec tion from hazard ous voltag es and  c urrents is req uired for all off-p remises 
(out of b uild ing ) trunks, lines, and  terminal installations. Both over-voltag e 
p rotec tion (lig htning, p ower ind uc tion, and  so forth), and  sneak c urrent 
p rotec tion are req uired . Sneak c urrent protec tors must b e either UL listed /CSA 
c ertified , or must c omp ly with loc al safety standard s.
Sneak c urrent p rotec tors must have a maximum rating  of 350 mA, and  a 
minimum voltag e rating  of 600V, or as req uired  b y loc al reg ulations. The following  
d evic es protec t the system from over-voltag es:
nAnalog  trunks use the 507B sneak p rotec tor or eq uivalent. Over-voltage 
p rotec tion is normally p rovided  b y the loc al telep hone c omp any.
nAnalog  voic e terminals use one of the following  typ es of c omb ined  
over-voltag e and  sneak c urrent p rotec tion, or eq uivalent:
— Carb on b loc k with heat c oil for UL c od e 4B1C
— Gas tub e with heat c oil for UL c od e 4B1E-W
— Solid  state with heat c oil for UL c ode 4C1S
nDCP and  ISDN-BRI terminals use the solid  state 4C3S-75 with heat c oil 
p rotec tor, or eq uivalent
nDS1/E1/T1 c irc uits req uire isolation from exp osed  fac ilities. This isolation 
may b e p rovid ed  b y a CSU (T1), LIU (E1), or other equip ment that 
p rovid es eq uivalent p rotec tion
Sneak Fuse Panels and Emergency Transfer Units
Ap p roximately eig ht inc hes (20 c m) of horizontal wall sp ac e is req uired  for eac h 
c olumn of sneak fuse panels. Horizontal wall sp ac e must also b e p rovided  for 
emergenc y transfer units.

2-6 Installation Requirements

110-Type Hardware
The trunk/auxiliary field  and  the d istrib ution field  are mounted  on the same wall. 
Eac h 110P-typ e terminal b loc k is 8.5 inc hes (21.6 c m) wid e. Vertic al p atc h c ord  
troug hs are 5.31 inc hes (13.4 c m) wid e and  horizontal p atc h c ord  troug hs are 23 
inc hes (58.4 c m) wid e.
Eac h 110A-typ e terminal b loc k is 10.81 inc hes (27.4 c m) wid e; however, no 
horizontal p atc h c ord  troug hs are used  and  the b loc ks are shorter than 
110P-typ e terminal b loc ks. This allows the 110A-typ e terminal bloc ks to be 
stac ked . Therefore, the 110A-typ e hard ware req uires less sp ac e than the 
110P-typ e hard ware on a p er-station b asis.
Cable Slack Manager
A Cab le Slac k Manag er is 32 inc hes (81.3 c m) wid e. Slac k manag ers are 
c ommonly used  in installations c onsisting  of c ab inet stac ks. The q uantity of slac k 
manag ers is d etermined  by d ivid ing  the total leng th of the MDF in inc hes 
(c entimeters) by 32 (81.3). A partial number of 0.4 or less should  b e round ed 
d own, and  a p artial numb er of 0.5 or more should  b e round ed  up  (for examp le: 
2.4 =  2 Cab le Slac k Manag ers and  2.5 =  3 Cab le Slac k Manag ers).
NOTE:
Cable c lamp s are req uired  in installations with Cab le Slac k Manag ers. At 
the rear of the c ab inets, on eac h rear g round  p late, install two c ab le c lamp s 
using  the sc rews p rovid ed . These c lamp s hold the 25-p air inp ut/output or 
MDF c ab les in p lac e.

The Model 507B sneak c urrent fuse panel, or eq uivalent, is rec ommend ed  for 
sneak c urrent p rotec tion. See Fi g u re  2 - 4
. The panel c ontains two 25-p air 
c onnec tors, fuse removal tool, and  fifty 220029 Sneak Fuses (and two sp ares).
Connec tor c ab les (B25A male to female) c onnec t the network interfac e to the 
sneak fuse p anel. Also, 157B c onnec ting  b loc ks eq uipp ed  with SCP-110

NOTE:
Sneak c urrent p rotec tors with a rating  of 350 mA at 600 volts must b e 
Underwriter’s Lab oratory (UL) listed  for d omestic  installation and  Canad ian 
Stand ard s Assoc iation (CSA) c ertified  for Canad ian installation.
nThe 507B inc lud es 52 sneak fuses and  two c ab les and  c an b e ord ered
