The High Pass Filter (HPF) blocks the POTS/ISDN signals towards the VTU, and

the Low Pass Filter (LPF) blocks the VDSL signal towards the Local Exchange

(VTU-O side) or telephone set (VTU-R side).

Synchronization

A bandplan is a partitioning of the frequency spectrum into non-overlapping

frequency bands, each of which is allocated for either upstream or downstream

transmission. ANSI and ETSI define a set of predefined VDSL BandPlan modes of

operation. The VDSL BandPlan shall be configurable on a per port basis. The

following bandplans are supported:

bandPlanAnnexA998 17A, 30A

bandPlanAnnexB998ADE 17a, 30a

bandPlanAnnexB998E 17a, 30a

DS1/E1 interface specifications

The business ONT supports structured, unstructured, and fractional DS1 (100 Ω) or

E1 (120 Ω/75 Ω) services. An external adapter is required for 75 Ω. You cannot mix

DS1 and E1 services on the same ONT. You must configure both ports for either DS1

or E1 on the same ONT.

The CES subsystem encapsulates DS1 or E1 traffic received at the RJ-48C port using

MEF-8 packetization as Ethernet layer 2 for transport across the GPON. The CES

encapsulation is removed before DS1 or E1 traffic from the GPON is sent to the DS1

or E1 lines at the subscriber side.
