OPTera Metro 3500 Multiservice Platform NTRN10AN Rel 12.1 Standard Iss 1 Apr 2004
Collocated OPTera Metro 3000 NE and dedicated STS at each site
Using a collocated OPTera Metro 3000 NE and dedicated STS at each site
provides the following values over a head-end ring node connection:
• For TDM traffic, it provides a termination point for electrical services
(DS1, DS3, EC1) and allows efficient bandwidth utilization of the OPTera
Metro 3500 STS-managed backbone network through VT grooming.
• For Ethernet traffic, it allows efficient transport through a Gigabit Ethernet
RPR connection to the OPTera Connect DX NE.
• It is a modular network design with low initial costs. That is, you can
collocate OPTera Metro 3000 NEs according to demand. Each NE can
support a mix of TDM and Ethernet traffic or you can dedicate NEs for
either TDM or Ethernet traffic.
Figure 2-70 on page 2-185 shows a configuration that transports TDM traffic
using a collocated OPTera Metro 3500 NE.
