Operation with an IP2000 control module
The Stinger Compact Remote ATM DSLAM unit can be also equipped with an IP2000
control module for stand-alone operation. The IP 2000 control module
(STGRRT-CM-IP2000-F) provides the control capabilities of a standard Stinger
control module, and also provides a fiber gigabit Ethernet port for end-user traffic.
Units manufactured and equipped for stand-alone operation with an IP2000 module
have a modified enclosure door. This door is manufactured with a 0.5 inch (1.3cm)
bulge in the door at the location of the fiber connector on the IP2000. This bulge
allows space for the curvilinear guide fiber cable to physically route the fiber light
guides downward (see Figure 1-3 on page 1-5 and Figure 3-24 on page 3-33).
Information in this document for basic configuration can be applied to the IP2000
module. However, for complete information about configuration of the IP capabilities
of this module, see the
Stinger Control Modules Configuration Guide
.
Hosted operation
The Stinger Compact Remote ATM DSLAM can function as a hosted optical network
unit (ONU), to extend the reach of a host Stinger unit in a central office. For hosted
operation, the Compact Remote ATM DSLAM unit is equipped with a control and
optics pack (COP). This circuit pack contains hardware to control the operation of
components in the local chassis, and a 155Mbps optical port for an optical connection
to a host Stinger unit. Management and configuration for the Stinger Compact
Remote ATM DSLAM is handled through the TAOS management interface on the
host Stinger unit.
Subscriber DSL lines are physically terminated on the Stinger Compact Remote
chassis. However, these lines appear as ATM connection endpoints within the TAOS
management interface for the host Stinger unit. Their configuration is also handled
through the host management interface. The optical link between the host Stinger
unit and a hosted Stinger CR ATM DSLAM unit is transparent to the ATM
connections.
