Now
- To date, access to alternative carriers has been via dial-up [indirect
access]:
- for example: a company has its lines provided by BT and
wishes to save money on outgoing calls.
- The company signs up with a carrier ‘An LCR Carrier: ALC’.
- To access ALC the customer’s equipment [eg telephone system]
automatically prefixes appropriate calls with an access code [eg 1xxx].
This access code tells the BT exchange to send the call to the ALC
network.
The future
- Indirect access using dial-up will continue indefinitely. It is the
easiest form of accessing an alternative carrier and offers swift control
regarding provisioning, alteration and cessation for both the carrier and
the customer.
- CPS will not replace indirect access using dial-up.
- Where CPS will become a useful tool is in the domestic market.
What is CPS?
- Carrier Pre Selection [CPS] does the same as indirect access using dial-up
but at the PTO’s exchange as opposed to on the customer’s equipment.
- The customer signs up with a carrier and informs the PTO [eg BT] that he
is now a subscriber to the carrier’s network. The customer/carrier also
informs the PTO what type of calls are to be routed to the carrier [eg all
calls; eg international only].
- Once the service has been provisioned by the PTO and the carrier the
customer dials the numbers in the normal manner and the PTO’s exchange
will insert an access code into the digit stream. This access code [8xxxx]
sends the call, where appropriate, to the carrier’s network.
- As with normal indirect access, an override code will be available to
allow calls to be forced over the PTO’s network.
Dealing with CPS
- In theory CPS is a wonderful idea and, as regards the domestic market, it
will become a cost effective tool. However, it presents a bundle of new
problems and risks to the customer and the carrier.
- We at SJG are LCR/ARS experts and therefore offer a range of services to
carriers, networks and communications/IT companies with regards to CPS:
CPS advisory service
- SJG offers an advisory service to carriers and resellers which fully
explores the CPS service and all of the hidden implications.
- This is designed as a preparatory measure before implementing a CPS
strategy and / or to provide a criteria for a solution path to deal with all
CPS issues.
CPS implementation service for Carriers
- It is no simple matter introducing CPS, SJG will completely set-up the CPS
service for carriers.
- This comprehensive service takes a carrier from non-CPS to an up and
running CPS capability.
- This includes network, sales, marketing, admin and technical
implementation.
CPS implementation service for Resellers
- Resellers who wish to continue with the levels of control and
flexibility they have with indirect access will need to have a CPS procedure
in place.
- SJG offer a comprehensive service to implement this ability.
CPS on-site: provisioning & implementation
- provisioning: existing on-site services from SJG - the LCR/ARS experts -
have been modified to enable SJG, and therefore its carrier clients, to
provide CPS. Such services would involve intricate site cli investigations,
LCR removal, call barring modification etc
- The best and safest way to implement CPS is to use SJG.
CPS on-site: solutions
- existing on-site services from SJG - the LCR/ARS experts - have been
modified to enable SJG, and therefore its carrier clients, to deal with the
incredible problems associated with CPS.
- Where CPS is involved terrible problems with the switches can occur
because of incorrect cli provisioning and customers leaving, joining,
changing carriers can end up with no outgoing calls at all [except 112,
999].
- This is just one of many, many pitfalls associated with CPS.
- All of the cps problem scenarios are explored & explained by the SJG
CPS advisory service.
- The best way to avoid cps problems is to use SJG.
- When CPS problems occur: they will and they will be bad: your best &
speediest fix is SJG.
More on CPS problems:
- A user, a maintainer, a carrier or a reseller will encounter severe
service problems because of a CPS issue. You will be in the position that
you can’t actually take control of the situation because the CPS service
will not allow it. Such problems are covered comprehensively by the SJG CPS advisory
service.
- When faced with such situations your best fix is SJG.
- SJG have the technical skills to resolve the issue and, of even more
significance, have the procedures in place.
