# System Numbering Plan SL2100

## System Numbering Plan SL2100

(OP)
We have 1st floor: 1-XX (100-199)
10th flo0r: 10-XX (1000-1099)
1st and 2nd Dial Digits: "1x" have Dial Digit Length is "3", type "Extension".
1st and 2nd Dial Digits: "10" have Dial Digit Length is "4", type "Extension".
So we can make a call form 1000 to 100, but can't call from 100 to 1000 (Dial "1", "0", "0" hear busy tone).
What is solution for this case?

### RE: System Numbering Plan SL2100

Logic 101. The solution is to fix your numbering plan.

Hi CoralTech
If we change EXT 100 to 101, then 1000 call 101 is okay, but 101 can't call 1000, when EXT 101 dial "1", "0", "0" -> hear vacant number (don't have EXT 100).
Do you have any ideas?

### RE: System Numbering Plan SL2100

1x cannot equal 3 Digit

Break out all your 1s as separate numbers = to extension digits & 100 cannot exist as a stand alone due to 10=4 digit

1x =0
10= 3 digit if you want 100-109 or 4 digit 1000-1009 Cant have both though
11= 3 digit
12= 3 digit
and so on down the line

Thanks Mitchell70, but customer requested "1st floor: 100-103, 10th flo0r: 1000-1003" then how to respond?

### RE: System Numbering Plan SL2100

You can always do *100 or #100, but you will have to change service codes as well. A digit can be designated as 3 or 4 digits in length, but not both.

### RE: System Numbering Plan SL2100

Without knowing the details of the customer's site it's very hard to give a solid answer,but I would recommend 4 digit dialing. Starting with 1### Depending on the type of place this is having as 1100 though through 1109. This will give you the opportunity to use 1000 For your 10th floor without reaching too much havoc on your system's dialing plan.
Floor 1 = 1100-1199
Floor 2.= 1200-1299
Floor 3 = 1300-1399
Floor 4- 9 the same in unison
Floor 10 = 1000-1099.

Cmd 11-01, 1x =4 or break out as each individually. JUST CANNOT USE 1X and 10 at the same time 1X overrides everything else.

### RE: System Numbering Plan SL2100

Just a point that may be worth considering and I may be wrong but couldn't you use F route programming to achieve this and shorten the interdigit timer a second or two. That way when dialling a three number, if the guest dials 101 and stops, it will get room 1 on the first floor but if they continue dialling before the timeout is up say 1001 they will get room 1 on the 10th floor (same would apply for 100 and 1000 but does any hotel have a room 0 on any floor?).

### RE: System Numbering Plan SL2100

Still won't work Ozzie. It's a logic issue. This is like basic programming 101 from back in college/HS. I'm actually surprised you can fit a 2100 in a 10 story hotel. I mean how many rooms per floor?

The amount of times I have had to fix numbering plan issues is staggering. People start out with 3 digit plans, clearly out grow it and don't change until it costs a lot in time and planning. Everything starts with the numbering plan. All other things are nonsense that can easily be addressed.

### RE: System Numbering Plan SL2100

@Coral tech

But that is the way single digit dialling works, you can have extension 1 and extension 100 on the same system, this has always been the case for hotel systems. The secret to it is to analyse the 4 digit numbers first and when a match isn't made (because the user only dialled 3 digits) it moves on to the 3 digit numbers and finds the match which then sends it to that station (F route allows you to analyse the digits dialled and route as you want).

Well I tried to do this as I am stuck at home following a minor operation yesterday and I have to admit defeat. it also occurs to me to ask how the OP is handling floor 9 as surely that would be his line access code (assuming they are in the US) It would be possible here in OZ as our line access code is 0 but they only sell the SL2100 here as a single chassis, you can't get an expansion chassis.

As for an SL2100 serving a 10 storey hotel, that would also depend on your mix of terminals, it can support 112 legacy and 112 VoIP so 224 stations but like you say it depends on how many rooms per floor.

@OzzieGeorge
As I know SL2100 support max. 112 stations (both legacy and IP). We can deloy for small hotel or guest house, motelâ€¦
In case using F-route, how to config in CMD 11-01 or more details?

@simjisn

See the edited post above.

### RE: System Numbering Plan SL2100

There was this one customer we had that needed more, so we tied 2 systems together next to each other with NetLink. Numbering was a challenge, but it worked.

Why not a 9100?

### RE: System Numbering Plan SL2100

On taller hotels, we generally use 7 as a leading digit. 71xx through 79xx for first nine floors and then 10xx, 11xx, 12xx, etc for higher floors.

Four digit extension numbers are going to work much better.
