IP traffic, can be seamlessly delivered to end-

users over the cable modem platform.

Standardization

In the US, cable operators formed a consor-

tium called CableLabs to accelerate the de-

velopment of standards within the cable in-

dustry. In Europe, tComLabs performs a

similar role. Other efforts are currently un-

derway in Europe and North America to

standardize voice over IP (VoIP) over cable

and home networking.

One of CableLabs’ recent standards regu-

lates the sending of data over cable. This ef-

fort resulted in the development of the data-

over-cable service interface specification

(DOCSIS) which was adopted as IEEE

802.14. An appendix to this standard ap-

plies to European television standards. The

standard was also adopted by tComLabs, a

consortium of European operators who co-

ordinated it as Euro-DOCSIS 1.0. (ETSI

standard, ES 201 488 V1.1.1). It is based on

the 1.1 RFI Version IO6, which is includ-

ed in tComLabs’ appendix to Euro-DOCSIS.

Every cable modem has to go through

DOCSIS certification by CableLabs. To

date, DOCSIS has gone through seventeen

certification waves. Each wave consists of a

set of lab tests and documentation to ensure

cable modem design compliance with es-

tablished specifications and standards.

Euro-DOCSIS requirements are certified by

tComLabs. They are currently in their third

wave of compliance testing.

VoIP

Many cable operators are eyeing voice over

IP as a major source of revenue and have

asked CableLabs to develop a standard,

known as PacketCable, which includes voice

as well as provisions for other kinds of media.

The standard prompted several enhance-

ments to the DOCSIS standard (DOCSIS

1.1), including quality of service (QoS) and

additional remote-management features.

Ericsson currently offers two cable modem products: the PipeRider HM200c and HM201c.

The HM200c is DOCSIS 1.0 certified and the HM201c is Euro-DOCSIS certified. The

HM200c has received conditional @Home certification. The PipeRiders connect to cus-

tomer premises equipment via USB and 10 Mbit/s Ethernet interfaces. A PipeLock security

button allows the user to isolate the LAN and WAN sides of the cable modem when it is

not in use, but keeps the modem attached to the system and available for instant access.

In accordance with a specification in the DOCSIS standard, the modem software can be

upgraded remotely by the cable operator. The HM200c/HM201c has been certified by reg-

ulatory bodies for use in the US, Canada, the EU, Japan, Korea, Australia, and China.

PacketCable and DOCSIS are trademarks

and/or trade dress of CableLabs or third par-

ties.
