Technical Support
Assistance in maintaining your installed system is available through the Regional
Technical Assistance Center (RTAC) and the Customer Technical Support
Organization (CTS). As shown in Figure 2, your single point of contact is the
RTAC. RTAC personnel troubleshoot field problems 24 hours a day over the phone
and, if necessary, on site. For technical assistance, simply call 1-800-225-RTAC.
One call guarantees support.
RTAC organizations are supported by a centralized CTS for transmission
products. The CTS maintains a close relationship with Bell Laboratories and other
Lucent Technologies organizations to expedite resolutions and maintain contact
with the development community. This association provides continuous
accessibility to every phase of a product life cycle and assures a prompt resolution
to all inquiries.
The CTS has also established a dial-up technical support medium called COACH.
COACH is a system of on-line support tools aimed at providing product news and
bulletins, diagnostic services, compatibility information, and on-line documents.
COACH tools provide you with the most up-to-date product information so that
problems are either prevented or quickly resolved.
Many Lucent Technologies transmission products including DDM-2000
Multiplexers are supported by COACH.
Once connected to COACH, the user specifies which product to access and
COACH grants the appropriate combination of tools and commands. The user
reaches each one of these tools and commands through a centralized,
menu-driven computer program. Every screen provides help in making
appropriate menu selections. COACH users will achieve proficiency quickly
because of the consistency of menu selections among products.
Figure 2. Product Support
The COACH tools reside on a dedicated time-share computer accessible over
toll-free lines and are available 24 hours a day, 7 days a week.
The following COACH tools are available:
