electronic tandem network (ETN)
A tandem tie-trunk network that has automatic  call-routing  cap ab ilities b ased  on the numb er 
d ialed  and  the most preferred  route available. Each switch in the network is assig ned  a uniq ue 
p rivate network offic e c od e (RNX), and  eac h voic e terminal is assigned  a unique extension.
Electronics Industries Association (EIA)
A trad e assoc iation of the elec tronic s ind ustry that establishes electrical and func tional stand ard s.
emergency transfer
If a major system failure occ urs, automatic  transfer is initiated  to a g roup  of telep hones c apab le of 
making outg oing  c alls. The system operates in this mode until the failure is repaired  and  the 
system automatic ally returns to normal operation. Also called  p ower-failure transfer.
EMI
Electromagnetic  interferenc e
end-to-end signaling
The transmission of touc h-tone sig nals g enerated b y d ialing  from a voic e terminal to remote 
comp uter equip ment. These d ig its are sent over the trunk as DTMF dig its whether the trunk 
sig naling  type is marked  as tone or rotary and  whether the orig inating station is tone or rotary. 
Examp le: a c all to a voic e-mail mac hine or automated -attend ant servic e. A connec tion is first 
estab lished  over an outg oing  trunk. Then ad ditional d ig its are d ialed to transmit information to be 
p rocessed b y the c omp uter eq uip ment.
enhanced private-switched communications service (EPSCS)
An analog  p rivate telec ommunic ations network based  on the No. 5 crossb ar and  1A ESS that 
p rovid es ad vanced  voic e and d ata telecommunications servic es to c ompanies with many
