OAM cells: Colt will prepare a presentation on their experience of use of Ethernet CFM.
Colt answer: “We think our CFM experience is not relevant because operators will
implement CFM in their networks, but will not give access to others.”

BROBA over Ethernet & WBA VDSL2
Multiple VLANs per service
• Other operators request max 2 VLAN of same QoS per LEX per Operator
• Possible in the current services: OLO identifies himself twice
 once as Operator A (e.g.: for residential market)
 once as Operator B (e.g.: for business market)

PPPoA/PPPoE/IPoE protocols
Optional implementations of forwarding modes for
BROBA over Ethernet
• 2 forwarding modes for GE_NT ( PPP aware and Residential bridge)
• Optional implementations for the resp. services P0, P1 , P3, P5:
Initial proposal: P0, P1, P3, P5 only in Residential Bridge mode:
Pro: transparent Ethernet service (BROBA on ATM is a transparent ATM service)
Contra: no PPPoA
New Belgacom proposal: P0 in PPP aware; P1, P3, P5 in Residential
Bridge in IPoE
This is the BGC retail implementation, except:
• No P1 nor P3 offered @ BGC retail
Pro:
• Support of PPPoA
• Conforms to the most popular usage of P0 (coupled to UBR): Fast Internet Access

ATM to Ethernet migration process
For dedicated VLAN’s
Suppose an OLO customer, without management VC,
but with user VCs (8/35) & (8/36)
• OLO orders new management VC eg (8/44)
• OLO orders new user VCs eg (8/39) & (8/40), over
Ethernet
• OLO reconfigures the user CPE with VCs (8/39) & (8/40)
and tests
• OLO cancels (8/35) & (8/36) and eventually also the
management VC (8/44)
07 July 2015
Slide 19
ATM to Ethernet migration process
For shared VLAN’s
• Olo verifies the capabilities of the user CPE:
• UBR/p0: PPPoA or PPPoE
• Nrt-VBR/p1 or rt-VBR/p3 or CBR/p5 :IPoEoA
• no IPoA !
• Olo orders migration
• BGC configures the new VC connections in the GE_NT aggregator, off-line
• At agreed moment, BGC switches in ASAM.

BROBA over Ethernet
XML content description
• The “BROBA XML Content Description” describes the XML messages
(message type, needed fields, formats, …)
• Limited impact on current document
 no impact on ordering of BROBA over ATM lines,
 no new XML,
 no process change.
• Adapted document (for BROBA over Ethernet with shared VLAN’s) to
provide first half of October.

Next Steps
So far,
• Belgacom roll-outs the GE-NT cards in the Belgacom network, without impacting
the existing BROBA service
• Belgacom submitted to BIPT an “Ethernet” version of BROBA (with shared
VLAN’s)
• Belgacom studies an “Ethernet” version of BROBA (with dedicated VLAN’s)
• Some features of this future offer are being discussed between Belgacom and the
OLO’s
What’s next:
• MoM of today’s meeting on Belgacom website
• Expected inputs of OLO’s & BGC: see MoMs
• Follow-up meeting : october 7th 2009
• Target date offer ready to order :
 March 2010 (with shared VLANs)
 June 2010 (with dedicated VLANs)
• Building outphasing workshop to be organized by Belgacom
