Planning & Programming Guide

PLANNING
Station Groups Determine for each station
Call locations,  Local
Interlata (In state toll)
Interstate Toll
International Toll
Allowed call types, DDD
Operator assisted
Toll Free
Service Codes
Allowed call times, Maximum of 8 periods are available
Allowed facilities local CO trunks
Foreign Exchange (FX)
Wide Area Telephone Service (WATS)
Tie Trunk/International Voice Gateway
Note for each station the TGAR and NCOS if programmed
Trunk Groups Determine for each trunk group:
Dialing patterns, The number of digits required to complete and identify each call type: 4, 7, 10, 11, or more.
Mandatory digits (is 1 required for a toll call?)
Preferred usage sequences Which trunk group will carry each call type at the lowest possible cost?
The second lowest cost?
The most expensive?
Permissions Note the TGAR for each trunk group
System Select system wide parameters
Use the above information to determine the minimum of each parameter that will be required, then increase it by at least 10% above expected growth estimates. Maximum number of location codes (ISDN networking)
Maximum number of Supplemental Digit Restriction Blocks
Maximum number of incoming trunk group exclusion tables
Maximum number of Digit Manipulation Tables
Maximum number of Route Lists
Maximum number of Free Calling Area Screening Tables
Maximum number of Free Special Number Screening Tables
Maximum number of Special Common Carrier entries
Select these options based upon local needs. BARS access code
Will second dial tone be provided?
Will expensive route warning tone be provided?
Will trunk group access restrictions be checked?
Will Off-hook or call back queuing be used?
PROGRAMMING
LD 86 Preliminaries FEAT ESN
MXLC =max. number of LOC codes
MXSD =max. number of Supplemental Digit Restriction blocks
MXIX =max. number of Incoming Trunk Group exclusion tables
MXDM =max. number of Digit Manipulation tables
MXRL =max. number of Route Lists
MXFC =max. number of Free Calling Area screening tables
MXFS =max. number of Free Special Number Screening tables
CDP (YES) NO coordinated dialing plan
MSCC x  x =max. number of SCC entries (0 - 7)
AC1  BARS access code
AC2 (NARS only)
DLTN (YES) NO provide second dial tone?
ERWT (YES) NO expensive route tone available?
Time of day restriction lists TOD (8 lists available, 0 defaults to all day, 7 or attendant's <RTC> key changes NCOS)
ETOD 1= Sunday 2= Monday . . . 7= Saturday
Apply restriction Controls RTCL YES
NMAP xx yy
xx= normal NCOS
yy= NCOS when TODS 7 active or <RTC> activated.
Digit Manipulation FEAT DGT
DMI xxx
xxx = Digit Manipulation Index number used in the Route List
DEL (0) - 19
- number of leading digits to be deleted
INST x . . . x
- leading digits to be inserted
SCCI (0) - 7
- index into the Special Common Carrier table
CTYP (NCHG)
- can change the call type, default is no change
LD 87 Network Restrictions for station NCOS FEAT NCTL
NCOS xx
xx= Network Class Of Service group number to be modified.
FRL x
x= Facility Restriction Level (0) - 7
Free Calling Area Screening FEAT FCAS
FCI xxx
xxx = assigned index number to be used in the route list (1 - 127)
NPA xxx or 1xxx
Area code to be screened.
NXX DENY or ALLOW
DENY nxx
nxx = Code or code range to be denied.
or
ALLOW nxx
nxx = Code or code range to allow.
Free Special Number Screening. FEAT FSN
FSNI xxx
xxx = Assigned index number to be used in the route list (1 - 255)
SPN xxx
xxx = Service code to be screened
xxx DENY or ALLOW
DENY supplemental digits to be denied.
or
ALLOW  supplemental digits to allow.
LD 86 Build each required Route List 
Note: Not all fields are shown.
FEAT RLB
RLI xxx
xxx = Assigned index number to be used in the Network Translation Check table.
ENTR xxx
xxx = position in this list
ROUT xxx
xxx = route number assigned in LD 16 (0 - 511)
TOD x
x = Time of day schedule 0 - 7
EXP (NO) YES
Give expensive route
FRL x
x = Facility Restriction Level (0 - 7) higher is more restrictive.
DMI xxx
xxx = Digit Manipulation Index
FCI xxx
xxx = Free Calling Area Screening Index number
FSNI xxx
xxx = Free Special Number Screening Index
LD 90 Build the Network Translation Check tables.  Since there are no "wild card" characters, but limited ranging is permitted, it is suggested that things will be easier in the long run if you define all 800 possible area codes, even though they are not as yet all in service.  This will use a trunk if an invalid number is dialed until the Telco. kills the call.  This traffic increase should be insignificant. FEAT NET
TRAN AC1
TYPE HNPA
HNPA xxx
xxx= home area code
FEAT NET
