FTTN works best where the loop plant has been designed using the “Serving Area Design”, placing cross-connect boxes within 5 kft of the subscriber.
This is often the case with SBC, BellSouth, and Qwest. With Verizon’s network being older and less “subdivision-y”, they don’t have as uniform deployment of cross connect cabinets.
IOCs typically deploy their cross connect cabinets at 12 kft distances. In these instances, other provisions need to be made to access the loops.

23. OSP Innovation – the OSP DSLAM
Sealed DSLAM design eliminates the need for:
Expensive cabinet enclosures
Noisy, power hungry heat exchangers
Costly site construction
3rd generation sealed DSLAM design
8+ years of engineering expertise in sealed DSLAM design
Over 45,000 units deployed in the field today
Lower total landed cost for a sealed DSLAM changes the broadband business case

24. Changing the Total Cost of Deployment
Deployment is greatly simplified using OSP DSLAMs
No new right of way
No new pad work
Significantly lower shipping costs
Installation doesn’t require a crane
Smaller crew onsite for installation
No expensive heat exchanger solutions
Lower power requirements
Electronics costs keep falling but total deployment costs aren’t getting any cheaper
Metal (i.e. cabinets) keeps climbing
Lower density areas can’t prove in due to first cost turn-ups

The 112P is a 24 port ADSL2+ Combo module in an OSP enclosure. The unit is part of a TA5000 network and utilizes the Voice Gateway in the TA5000 network for GR303 connectivity to a CL5 switch. There are 2 versions of the TA1124P available – HDSL4 fed, or GE fed.
The TA1124P provides the most cost effective way to address rural markets without the need for costly cabinet installations.

29. Advancements in FTTN: VDSL2 Vectoring
What Vectoring Provides?
Eliminates self cross-talk on short copper loops
Significant gains on short loops (< 3 kft)
Deployment Guidelines for Vectoring
Short loop nature of this technology leads to smaller node sizes
Need small-form-factor, remote DSLAMs to take advantage of cross-talk cancellation capabilities of vectoring
VDSL2 with vectoring is ideally suited for remote node deployments

30. Reach for NBP Target Rates
Nominal Rates based on measured Profile 17a performance with 12 disturber w.c. self crosstalk, V-denotes measured performance in -140 dBm/Hz white noise, approximately the limit that can be achieved with vectoring. Profile 30a may boost upstream reach at high rates
