[Asterisk-Users] T1 Line install.. (UK Muppet)

[Dan Austin]

In a way Europe does make this easy, at the expense of choice.
These questionaires cover the gamut of standard analog lines to
hi-cap service, and ISDN hi-cap.

An E1 is almost (maybe always) ISDN, where a T1 is not, and a PRI 
is.  Consider it a cultural quirk.  Both are 24 channels, delivered
on exactly the same telco gear.  A T1 suggest inband signalling for
each channel, and no advanced features (like caller id is advanced).
A PRI is functionally identical to an E1, with a D channel for call
control. 

So if you want a similar service to what you get with an E1, you want
to order a ciruit whit these features:
B8ZS
ESF
24 channels
PRI
NFAS is no for a single span
1 D-Channel
NIPRI		(National signalling is common. Many other choices
exist)
2-Way trunk (otherwise it is inbound only)
DID		(Number range provided by you carrier)
Billing #	(Number range provided by you carrier)
PIC is your long distance carrier

These are the key elements, and should get you going.

Subject: [Asterisk-Users] T1 Line install.. (UK Muppet)

Hi all, Muppet from the UK asking for help

We are just about to have a T1 line installed in our office in Dallas
and "Advantex" the supplier has sent a questionnaire asking a number of
questions. I have put the question area at the bottom of the email, we
will be using Digium's hardware. could anybody help :-)

In the UK when I asked for a E1, number of trunks required and the
number of DID numbers, then they stick the socket on the wall! No mass
question... I feel I'm a little out of my depth.

Thanks in Advance for any help.

============= Questionnaire Follows =================
1.  DS1 Facilities Required:

- Superframe or Extended (ESF/SF)?
- Line Coding (B8ZS,AMI,. Etc.)?
- Number of DS1 facilities required?
- Channel numbers used for this trunk group?


2.  Circuit Signaling  (DS0 or DS1 Signal):

DSO Analog Line Trunk Interface
    2 wire, 4 wire, (or "na", not applicable)?
- Supervision 
    Loop Start, Ground Start, Reverse Battery, E & M
    "DNIS - Dialed Number Identification service"
    Not applicable with DS0 Analog Line trunks.

DS1 Digital Signal : Digital Interface
- Supervision 
    Loop Start, Ground Start, E & M
- In-Band or Robbed Bit (E&M) signaling? (Y/N)
- CO  Supplied Dial tone (Y/N)

DS1 Digital Signal:  ISDN PRI Only
 - Primary Rate Interface (ISDN PRI) 
 - If multiple DS1s, Does the customer want 
   "Non-Facility Associated Signaling"? (NFAS) (Y/N)  

   If No, Does the customer want One D-Channel per DS1, 
   or 1 D-Channels for all  DS1s.  How many D-Channels?

   If NFAS=Yes,  Number of D-Channels Required  "TWO"

 - (PRI ISDN Protocol)= example National PRI  (NIPRI)
     NIPRI, NTNAPRI, U449PRI, U459PRI, N449PRI

3.  Trunk Group Billing Telephone Number (10 digit):

4.  Trunk Group Originating Area Code for PBX

5.  Calling Scope (Basic, Basic+, Extended, Metro, Metro+)?

6.   Primary Interexchange Carrier (PIC)

7.  NPA/NXX Call Blocking ( 700, 900, 976)

8.  Trunk Group Directional call flow and Member numbering:
        (If sub-grouped, select subgroup rollover)
   - 2-Way,  1-Way Into PBX, or 1-Way Out of PBX
   - Member Numbering (i.e. 0001 thru 0024)

9.  Trunk Member selection

-  Selection for calls originating at the PBX toward the Central Office
(CO)
   Asending (ASEQ), Desending (DSEQ), Most Idle (MIDL), Least Idle
(LIDL)
-  Selection for calls terminating to the PBX  from the Central Office
(CO)
   Asending (ASEQ), Desending (DSEQ), Most Idle (MIDL), Least Idle
(LIDL)

10.  Direct Inward Dial to PBX - DID (Y/N):
- Number or Number Blocks routed toward PBX (i.e. 972-668-20xx)
- Porting Coordination Required (Y/N)?            
- Number of digits to outpulse (None, 4, 7, 10 digits) to PBX?

11.  Inband Ringing required from the CO when terminating calls to PBX
(Y/N)?

12.  NON-PRI DS1Switching - Start Signaling and Digit Pulsing for
In-Band 
        Signaling for NON-PRI DS1:
- CO Incoming Start Signaling for calls originating at the PBX
(ISTARTSG)
        Start Signal expected by the PBX, sent by the CO telling the 
        PBX to begin sending digits to the CO for collection.
        - Wink Start, Delay Dial, Immediate Dial, Dialtone, Loop Start, 
                Grd Start

- CO Incoming Digit Pulsing for calls originating at the PBX (IPULSTYP)
        Type of digits sent from the PBX to CO after the PBX 
        receives the start signal (ISTARTSG) from the CO
        - Dial Pulse, DT/ DTMF, MF, NP/No Pulsing

- CO Outgoing Start Signaling for calls terminating to the PBX
(OSTARTSG)
        Start Signal expected by the CO, sent by the PBX telling the 
        CO to begin sending digits to the PBX for collection.
        - Wink Start, Immediate Dial, Delay Dial, Loop Start, Grd Start


- CO Outgoing Digit Pulsing for calls terminating to the PBX (OPULSTYP)
        Type of digits sent from the CO to the PBX after the CO
receives 
        the start signal (OSTARTSG) fom the PBX
        - Dial Pulse, DT/ DTMF, MF, NP/No Pulsing

13. Manufacturer & Model of PBX.
