Predictika · Ethernet leased line and SIP trunk quote check, UK business connectivity

A sales assistant's leased line quote, checked before it goes to the customer

A sales assistant prepares a quote for a business Ethernet leased line with an optional SIP voice trunk and says it is ready to send. Before it goes out, the assistant sends it to Predictika's validator, which checks the bearer, bandwidth, resilience, service level, SIP voice, construction charges, contract term, lead time and discount together, prices the circuit, and reports every problem it finds in one pass.

Scope: Business Ethernet leased line quotes with an optional SIP trunk, priced in pounds sterling: bearer and bandwidth fit, resilience and service level, SIP channels and emergency-address validation, excess construction charges, contract term, lead time and discount authority. All prices, charges, lead times and thresholds are illustrative estimates, not a price list. A quote check, not an order. See everything this validator covers

This validator checks any single-site leased line quote of this kind against the rules below, not just the scenarios shown.

  • Bearer and bandwidth — the bandwidth must fit the bearer, a 10 Gbit/s bearer is offered only where 10G fibre is built, and it needs a term of 36 months or more.
  • Resilience and service level — a diverse second route needs a second exchange at the site, and the Premium service level is offered only on a resilient circuit.
  • SIP voice — SIP channels are sized against the circuit (a share of the bandwidth is reserved for voice) and need a validated emergency-services (999) address.
  • Construction charges — charges for distance from the nearest fibre are computed from the site; the customer must accept them, a very large charge needs a site survey, and any charge needs a term of 36 months or more.
  • Lead time and discount — the delivery time grows with diversity and construction, a short wait can be expedited with approval, and the extra discount a rep, a manager or the deal desk can grant depends on the contract value.

Any quote for one site that touches these rules is in scope, not only the scenarios pictured here. Not checked: real availability at a postcode, actual price lists, taxes, credit checks, contract wording, and the accuracy of the facts the caller states. Prices are in pounds sterling excluding VAT.

The sales assistantTakes the circuit request from the customer, prepares the quote and says it is ready to send.

Where a rules-based quoting tool gets this wrong
Click to expand
    
Our assessment of what a typical rules-based quoting tool (one rule per field, each limit checked on its own) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtA rules-based quoting toolPredictika
A limit that depends on another choiceOnly with care
The bandwidth that is allowed depends on the bearer, and the Premium service level depends on resilience, so each pairing needs its own rule and someone has to keep the list complete.		Bearer, bandwidth, resilience and service level are fields of the same request and are checked together.
A charge computed from the site that changes what is allowedOnly with workarounds
Distance from fibre sets the construction charge, the charge then forces a 36-month term and adds weeks to the lead time, and a tool that prices first and validates later misses the knock-on effects.		The construction charge, the term and the lead time are worked out in one pass, so a short term or a short wait is flagged in the same answer as the charge.
Approval paths that depend on valueOnly with care
Who can approve a discount depends on the contract value, which itself depends on the term and the discount, so the thresholds have to be hand-maintained.		The contract value is computed first and the discount authority is read from it.
Every problem returned in one answerOnly with workarounds
Quote forms usually stop at the first failing field, so the rep fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The bandwidth does not fit the bearer.
2A 10 Gbit/s bearer is not offered where 10G fibre is not built.
3A 10 Gbit/s bearer needs a term of at least 36 months.
4Diverse routing needs a second exchange at the site.
5The Premium service level is only offered on a resilient circuit.
6SIP channels do not fit within the voice share of the bandwidth.
7SIP numbers cannot be activated until the emergency-services (999) address is validated.
8A very large construction charge needs a site survey.
9The customer must accept the excess construction charge.
10A circuit with a construction charge needs a term of at least 36 months.
11The requested delivery time is too short, even with an expedite.
12The requested delivery time needs an expedite approval.
13The extra discount exceeds what anyone can approve.
14The extra discount needs a manager or the deal desk to approve it.

The recorded result of the validator for each scenario on this page: the request the AI agent sent, the verdict, and every finding, in the order they appear above.

    
1. A one-gigabit London circuit with 300 SIP channels: A premium London circuit with SIP voice, three problems

    
The agent's request. Please check this quote for Harlow and Pryce LLP at the London EC2 office: a 1 Gbit/s service on a 100 Mbit/s bearer, standard routing with the Premium service level, 300 SIP channels with the emergency address not yet validated, on a 36-month term wanted in 75 days. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Bandwidth does not fit the bearer. The 1 Gbit/s bandwidth does not fit the 100 Mbit/s bearer, which carries 10 to 100 Mbps.
    • 
      
  • Premium service level needs a resilient circuit. The Premium service level is only offered on a resilient circuit (Option1 or Option2), and this one is not resilient.
    • 
      
  • Emergency address not validated. SIP numbers cannot be activated until the emergency-services (999) address is validated.
    • 
      
  • Price estimate. The engine priced it at GBP 2,888 per month, GBP 103,968 over 36 months, but a blocked quote cannot be sent.
    • 
    

    
2. A one-gigabit London circuit with 300 SIP channels: The agent resubmits after fixing the errors

    
The agent's request. Please check this quote again for Harlow and Pryce LLP at the London EC2 office: the bearer is now 1 Gbit/s, with standard routing, the Premium service level, 300 SIP channels with the emergency address not yet validated, on a 36-month term wanted in 75 days. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Premium service level needs a resilient circuit. The Premium service level is only offered on a resilient circuit (Option1 or Option2), and this one is not resilient.
    • 
      
  • Emergency address not validated. SIP numbers cannot be activated until the emergency-services (999) address is validated.
    • 
      
  • Price estimate. The engine priced it at GBP 2,945 per month, GBP 106,020 over 36 months, but a blocked quote cannot be sent.
    • 
    

    
3. A one-gigabit London circuit with 300 SIP channels: The agent resubmits after fixing the errors

    
The agent's request. Please check this quote again for Harlow and Pryce LLP at the London EC2 office: a 1 Gbit/s service on a 1 Gbit/s bearer with a second bearer on the same route (Option1), the Premium service level, 300 SIP channels with the emergency address now validated, on a 36-month term wanted in 75 days. It is ready to send.

    
Verdict: Allowed.

    
    
      
  • Price estimate. The engine priced it at GBP 3,477 per month, GBP 125,172 over 36 months.
    • 
    

    
4. A Manchester warehouse 450 m from fibre: A 500 Mbit/s circuit at a warehouse far from fibre

    
The agent's request. Please check this quote for Ainsley Freight at the Manchester warehouse: a 500 Mbit/s service on a 1 Gbit/s bearer, standard routing and service level, on a 12-month term wanted in 60 days. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Construction charge needs a longer term. A circuit with excess construction charges needs a term of at least 36 months, not 12.
    • 
      
  • Delivery time too short. The circuit needs about 115 days and 60 days is more than two weeks short, beyond what an expedite can cover.
    • 
      
  • Construction charge to accept. The site is 450 m from fibre, and the estimated excess construction charge of GBP 7,500 (per route) must be accepted by the customer.
    • 
      
  • Price estimate. The engine priced it at GBP 580 per month plus GBP 10,000 one time, GBP 16,960 over 12 months, but a blocked quote cannot be sent.
    • 
    

    
5. A Manchester warehouse 450 m from fibre: The agent resubmits after fixing the errors

    
The agent's request. Please check this quote again for Ainsley Freight at the Manchester warehouse: a 500 Mbit/s service on a 1 Gbit/s bearer, standard routing and service level, now on a 36-month term wanted in 105 days. It is ready to send.

    
Verdict: Needs approval.

    
    
      
  • Construction charge to accept. The site is 450 m from fibre, and the estimated excess construction charge of GBP 7,500 (per route) must be accepted by the customer.
    • 
      
  • Expedite approval. The circuit needs about 115 days and the customer wants 105, so an expedite approval is needed.
    • 
      
  • Price estimate. The engine priced it at GBP 551 per month plus GBP 7,500 one time, GBP 27,336 over 36 months. It cannot be released until both approvals are given.

6. A Cardiff circuit with an extra discount: A 20 percent extra discount on a small Cardiff circuit

    
The agent's request. Please check this quote for Tregarth Dental at the Cardiff branch: a 50 Mbit/s service on a 100 Mbit/s bearer, standard routing and service level, on a 36-month term wanted in 75 days, with a 20 percent extra discount. It is ready to send.

    
Verdict: Blocked.

    
    
      
  • Discount too high. A 20 percent extra discount exceeds the 15 percent that anyone can approve at this contract value (GBP 10,260 before the extra discount).
    • 
      
  • Price estimate. The engine priced it at GBP 225 per month, GBP 8,100 over 36 months, but a blocked quote cannot be sent.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. A sales assistant prepares a quote for a business Ethernet leased line with an optional SIP voice trunk and says it is ready to send. Before it goes out, the assistant sends it to Predictika's validator, which checks the bearer, bandwidth, resilience, service level, SIP voice, construction charges, contract term, lead time and discount together, prices the circuit, and reports every problem it finds in one pass.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please check this quote for Harlow and Pryce LLP at the London EC2 office: a 1 Gbit/s service on a 100 Mbit/s bearer. It is ready to send. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The 1 Gbit/s bandwidth does not fit the 100 Mbit/s bearer, which carries 10 to 100 Mbps. The Premium service level is only offered on a resilient circuit (Option1 or Option2), and this one is not resilient. SIP numbers cannot be activated until the emergency-services (999) address is validated.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a limit that depends on another choice, a rules-based quoting tool is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the bearer to 1 Gbit/s.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with two findings, all in one answer. The Premium service level is only offered on a resilient circuit (Option1 or Option2), and this one is not resilient. SIP numbers cannot be activated until the emergency-services (999) address is validated.
    12. 
      
  12. One finding cleared. Still blocking: Premium service level needs a resilient circuit and emergency address not validated.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the resilience to Option1 (second bearer) and the emergency address validated to yes.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. Both earlier findings are cleared.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
