If longer reach or more bandwidth is needed, multiple pairs can be aggregated
to increase service potential.
VDSL2 is not particularly effective as a business service because it lacks a lot of upstream
capacity at mid- and long-reach distances. Business users most often want high
upstream, as well as downstream, bandwidth. Backup storage, e-mail, VoIP, and so on,
all require high-quality upstream connectivity. Although 10PASS-TS can be configured
to provide more upstream capacity, it is generally very distance limited.
Limitations of 2BASE-TL
Just as 10PASS-TS is targeted at residential applications, 2BASE-TL is targeted at
business applications. It is not as effective a residential technology because it lacks
triple-play asymmetric capabilities and also does not support simultaneous voice
(???POTS???) services. 2BASE-TL is targeted as a next-generation T1/E1 service replacement
and can be used in an analogous manner to today??™s T1/E1 services??”just with
more bandwidth and higher resiliency!
Benefits and Shortcomings
The Mid-Band Ethernet Technologies discussed here can be applied to solve both business
and residential applications.
