G.DMT
/ G.lite Offerings From Familiar Vendors
We have summarized
the offerings of the vendors we hear mentioned most often in conversations
with our customers about DSL. At least 30 other vendors offer or plan
to offer more than 100 other DSL products, including many for G.DMT /
G.lite service. This is not meant as an endorsement of the vendors or
products listed, or a criticism of the very large number not included.
Note:
- G.DMT line
cards should interoperate with both G.DMT and G.lite CPE, making
them versatile where both types of service are offered. G.lite line
cards interoperate only with G.lite CPE, but usually support
more lines per card, making the cost- per- port lower where only G.lite
is offered.
- Most of the
products listed have capabilities beyond the G.DMT / G.lite transport
and POTS features mentioned here, e.g., mount SDSL, HDSL, or VDSL line
cards in the same shelf.
