DDM-2000 FiberReach Service Applications
2
This section describes specific service applications. In addition to traditional
telephony, DS1, and T1 extension services, the following are examples of specific
service applications utilizing DDM-2000 FiberReach Multiplexers.
LAN/WAN Data Networking: DS3 Data Services
2
FiberReach Release 3.1 introduced a new DS3 Data Services Interface circuit
pack (BBG19) for use with data edge devices.
Increasing demands for data and multimedia applications have led to a significant
growth in LAN service needs among business customers. These service needs
have been focused on providing interconnection of business customer LANs over
a wide area network (WAN). To transport these LAN interconnect data services
over the public network, LAN routers and concentrators collect the data at a LAN
location and map it into traditional telephone network transmission signals (for
example, DS1 or DS3). These telephony signals can then be transmitted to wide
area locations where the data can be mapped onto the LAN at that location.
DDM-2000 FiberReach Multiplexers are ideally suited to serving the growing
demands for such WAN services. DDM-2000 FiberReach multiplexers can
interface to an external LAN/ATM switch via DS3 interfaces (see Figure 2-19 and
Figure 2-22). Using such an external LAN/ATM switch approach, DDM-2000
FiberReach Mulitplexers can provide the necessary transport capabilities to meet
the business customer LAN interconnect service needs. Delivering LAN
interconnect services using DDM-2000 provides the same high level of reliability
and availability for these services as is supported for all other premium business
services — this includes full STS-1 path-switching in ring configurations.
