Service Process Automation Control Engine is automated provisioning and
problem management system which enables complex workflow processes to be
defined and executed. It utilizes Clarify's Clear Support package, which
has been customized and enhanced with interfaces to other BT operational
support systems. SPACE is an integral part of BT Wholesale's strategic OSS
architecture comprising of major packaged applications such as SIEBEL
(Customer Management), CLARIFY (Service Provisioning & Fault Management),
CRAMER (Network Management) and GENEVA (Billing). SPACE Provisioning
supports Local Loop Unbundling & Wholesale Calls. Wholesale Calls is a
telephony product, enabling Service Providers to offer a branded telephony
calls service to their own End Users using the BT network. The Wholesale
Calls product is aimed at Service Providers (SP's), meeting the Ofcom
definition, who want to offer telephony services to their customers but for
a variety of reasons do not want to operate their own network. The
service is only available on a BT maintained line. BT will provide a
consolidated monthly bill to the SP for all of their call charges. The SP
is responsible for setting its own retail call charges and for billing its
End Users.
The LLU customers of BT post their orders via eCo interface. The orders may
be of Provide or Transfer type. The entries go into CSS main database and
the process progresses. CSS is synchronised with the actual processing
taking place at SPACE time-to-time. If some error occurs, the process is
stuck and is needed to be handled by SPACE Repair system. An SPACE agent
needs to investigate the fault and progress the order as well as
synchronising SPACE database with CSS.

online telecom,Germeny
The "Terminate Customer" at T-Online process distinguishes between definite
and ambiguous terminations. It contains all steps beginning with the
termination request from the customer to the termination of the customer
profile in all relevant systems (service, billing etc.). This process can
be triggered by manual
identification of a customer by a CSR or by a file interface
("Fremddatei"). A definite termination requires a letter, email or fax with
the customers' signature. As an exception, a termination via telephone is
also accepted after a check of the customer's identity. All other
terminations are considered as ambiguous. In this case, the customers are
contacted and asked to clarify the situation. The process termination can
be started via a written document or via phone.
