main distribution frame (MDF)
A devic e that mounts to the wall inside the system eq uipment room. The MDF p rovid es a 
connec tion p oint from outsid e telep hone lines to the PBX switc h and  to the insid e telep hone 
stations.
main-satellite-tributary
A private network c onfiguration that c an either stand  alone or ac cess an ETN. A main switch 
p rovid es interconnection, via tie trunks, with one or more sub tend ing  switc hes, c alled  satellites; all 
attend ant p ositions for the main/satellite config uration; and  ac c ess to and  from the pub lic  network. 
To a user outsid e the c omp lex, a main/satellite config uration ap p ears as one switc h, with one listed  
d irec tory number (LDN). A trib utary switch is connec ted  to the main switc h via tie trunks, b ut has 
its own attend ant p ositions and LDN.
maintenance
Activities involved  in keep ing  a telecommunications system in p rop er working c ond ition: the 
d etection and  isolation of software and  hard ware faults, and  automatic  and  manual rec overy from 
these faults.
management terminal
The terminal that is used  b y the system administrator to administer the switc h. The terminal may 
also b e used  to ac c ess the BCMS feature.
major alarm
An ind ication of a failure that has c aused  critic al d egrad ation of servic e and requires immed iate 
attention. Major alarms are automatically d isp layed  on LEDs on the attend ant c onsole and 
maintenanc e or alarming  c irc uit p ac k, log g ed  to the alarm log , and rep orted to a remote 
maintenanc e fac ility, if ap p lic ab le.
Manual-In work mode
One of four ag ent work modes: the mod e in which an agent is read y to p roc ess another c all 
manually. See 
Auto-In Work mod e for a contrast.

sep arate from H0, H11, and  H12 ISDN c hannels. The emerg ing  N x DS0 ISDN multirate c ircuit 
mod e b earer servic e will p rovid e c irc uit-switc hed  c alls with d ata-rate multip les of 64 kb p s up to 
1536 kb p s on a T1 facility or up  to 1920 kb p s on an E1 fac ility. In the switc h, N x DS0 channels will

is, manually map  call app earances and  feature buttons onto some other natively sup p orted  
terminal type).

Nonfacility-associated signaling (NFAS)
A method that allows multip le T1 and /or E1 fac ilities to share a sing le D-c hannel to form an 
ISDN-PRI. If D-c hannel b ackup is not used, one fac ility is config ured  with a D-c hannel, and  the 
other fac ilities that share the D-c hannel are c onfigured  without D-channels. If D-channel b ackup is 
used , two facilities are c onfigured  to have D-c hannels (one D-c hannel on each fac ility), and  the 
other facilities that share the D-c hannels are config ured without D-c hannels.
