Release 8.2
Installation and Maintenance for Survivable 
Remote EPN
Important information:
The Survivable Remote EPN (SREPN) is a disaster recovery operation rather 
than an additional reliability option.  As such, the SREPN, if administered properly, 
provides phone service to users on the remote EPN when the link to the main R8r 
processor fails or is broken, or when the R8r processor or center stage fails.
The SREPN can be both a single carrier cabinet and a multicarrier cabinet.  The 
survivable remote processor (SRP) is available only as a single carrier cabinet 
and does not hold any port cards.  You install and administer the SRP (with its 
associated SREPN) as if it were a standalone R8si with its own dial plan and 
AAR/ARS patterns.  This means that you must administer the SRP (
in addition to 
the R8r PPN
) for all phones and other equipment connected to SREPN.  Ideally, 
you will administer equipment on the SRP to duplicate, as much as possible, the 
service provided by the R8r PPN.  
Given that the R8r PPN is independantly 
administered from the SRP, only those translations administered on the SRP will 
operate when a failure occurs.

Your Responsibility for Your System’s Security
Toll fraud is the unauthorized use of your telecommunications system 
by an unauthorized party, for example, persons other than your com-
pany’s employees, agents, subcontractors, or persons working on your 
company’s behalf. Note that there may be a risk of toll fraud associated 
with your telecommunications system and, if toll fraud occurs, it can 
result in substantial additional charges for your telecommunications 
services.
You and your system manager are responsible for the security of your 
system, such as programming and configuring your equipment to pre-
vent unauthorized use. The system manager is also responsible for 
reading all installation, instruction, and system administration docu-
ments provided with this product in order to fully understand the fea-
tures that can introduce risk of toll fraud and the steps that can be taken 
to reduce that risk. Lucent Technologies does not warrant that this 
product is immune from or will prevent unauthorized use of com-
mon-carrier telecommunication services or facilities accessed through 
or connected to it. Lucent Technologies will not be responsible for any 
charges that result from such unauthorized use.
Lucent Technologies Fraud Intervention
If you suspect that you are being victimized by toll fraud and you need 
technical support or assistance, call Technical Service Center Toll 
Fraud Intervention Hotline at 1 800 643-2353 or contact your local 
Lucent representative.
Federal Communications Commission Statement
Part 15: Class A Statement. This equipment has been tested and found 
to comply with the limits for a Class A digital device, pursuant to Part 
15 of the FCC Rules. These limits are designed to provide reasonable 
protection against harmful interference when the equipment is operated 
in a commercial environment. This equipment generates, uses, and can 
radiate radio-frequency energy and, if not installed and used in accor-
dance with the instructions, may cause harmful interference to radio 
communications. Operation of this equipment in a residential area is 
likely to cause harmful interference, in which case the user will be 
required to correct the interference at his own expense.
Part 68: Network Registration Number. This equipment is registered 
with the FCC in accordance with Part 68 of the FCC Rules. It is identi-
fied by FCC registration number AS593M-13283-MF-E.
Part 68: Answer-Supervision Signaling. Allowing this equipment to be 
operated in a manner that does not provide proper answer-supervision 
signaling is in violation of Part 68 Rules. This equipment returns 
answer-supervision signals to the public switched network when:
• Answered by the called station
• Answered by the attendant
• Routed to a recorded announcement that can be adminis-
tered by the CPE user
This equipment returns answer-supervision signals on all DID calls 
forwarded back to the public switched telephone network. Permissible 
exceptions are: 
• A call is unanswered
• A busy tone is received
• A reorder tone is receivedCanadian Department of Communications (DOC)
Interference Information
This digital apparatus does not exceed the Class A limits for radio 
noise emissions set out in the radio interference regulations of the 
Canadian Department of Communications.

EPN c an b e loc ated  in either multic arrier or sing le c arrier c ab inets. SREPN is a 
d isaster rec overy operation rather than an ad d itional reliability op tion.
The Survivab le Remote Proc essor (SRP) is a TN790-b ased  p roc essor c omp lex 
c olloc ated  with the remote EPN c abinet. The SRP and  its EPN c ab inet are 
connected with fiber optic cabling.
