The charge for migration to a cabinet do not
reflect costs

• A migration is the move of a Customers Exchange
  based services to cabinet based services.
• A migration occurs when equipment is installed in
  a distribution cabinet.
• The draft STD replaces the STP POA charge with
  one for 34.43 per line based on erroneous
  application of information.
• Actual costs Chorus faces for the work are not
  always on a by line basis.
• Hence based on draft STD Chorus can only recover
  some of the cost of migrating broadband lines.

Chorus revenue shortfall is demonstrated by this
migration example

• Our example is based on a total of 400 lines
  running from the Exchange to a Distribution
  Cabinet. Of these lines, 325 are working
  lines, comprised of
• 200 POTS lines (both retailed and resold by
  Telecom Wholesale to Access Seekers)
• 120 broadband lines (both retailed and resold by
  Telecom Wholesale to Access Seekers as Wholesale
  Broadband Solutions or a bitstream service, e.g.
  UBA or Commercial UBS) and
• 5 UCLL lines that have been unbundled by an
  Access Seeker.
• The actual costs in this example have been
  provided to commission

Before project the copper lines run through a
passive cabinet

• Services are fed from Exchange-based equipment
  via tie cables to the MDF and hence to a passive
  distribution cabinet via a 400-pair feeder cable.
  At the cabinet, another jumper connects this
  feeder cable to one of 1200 pairs in distribution
  cables running to End Users premises.

Phase I - installation of cabinet and migration
of copper

• All the copper pairs, working or not, in the
  Passive Cabinet are transferred to the
  Distribution Cabinet at the one time.
• All services still provided from exchange
• Chorus is charged a lump sum fee for this work.

6
Phase II - Connection of lines to Distribution
Cabinet equipment

• Chorus contractors connect the 120 broadband
  lines served by Telecom to the cabinet-based
  equipment. Simultaneously they remove the
  connection to the Exchange-based equipment.
• Chorus is charged a lump sum fee for this work.

7
Phase III - Subsequent Migration toDistribution
Cabinet equipment

• Chorus contractors connect the 5 broadband lines
  served by Access Seeker to the cabinet-based
  equipment. Simultaneously removing the
  connection to the Exchange-based equipment.
• Chorus is charged a per line fee for this work.

Migration charge should reflect underlying cost

• The proposed 34.43 charge in the draft STD for
  migration at the time of initial cabinet
  installation should be POA based on costs.
• Chorus proposes that either
• the cost of phase I could be included as part of
  the cost of a Distribution Cabinet, recovered
  through rack space charge. Phase II costs being
  shared proportionally by customers unbundling
  that Distribution Cabinet or
• the cost of both phases I and II could be shared
  proportionally by customers unbundling that
  Distribution Cabinet.
• The charge for an initial migration should be a
  POA charge, migration at a later date should be
  fixed cost per line, both based on field services
  costs plus a 10 contribution to common costs.

9
The migration charge should be

• Charge for an initial migration should be a POA
  charge, based on field services costs plus a 10
  contribution to common costs.
• Charge for migration at a later date when
  additional equipment installed in cabinet should
  be fixed cost per line, based on field services
  costs plus a 10 contribution to common costs.
• 130.23, or
• 97.67 for 10 or more Migrations at the same time
  and to the same cabinet.
