2Wire, Inc.[edit]

2Wire, Inc. was (between 1998 and 2010) a home networking Customer Premises Equipment (CPE) manufacturer that provided telecommunications companies with hardware, software, service platforms, and remote CPE management systems. The company was headquartered in San Jose, California, in the Silicon Valley.

  • In July 2010, the company employed approximately 1,600 employees globally, including 550 in R&D, sales and administration, 450 in customer care and 600 agency employees in five U.S. offices and an additional nine offices around the world.
  • The 2Wire HomePortal residential gateways were distributed by broadband service providers such as AT&T, Embarq, windstream and Qwest in the United States, Bell in Canada, Telmex in Mexico, BT Group in the United Kingdom, Telstra in Australia and SingTel in Singapore.
  • In July 2010, Pace plc of the United Kingdom agreed to buy 2Wire for $475m (£307m).

History[edit]

2Wire was founded in 1998 by Brian Hinman (who also founded PictureTel and Polycom),

Pasquale Romano, Brad Kayton, and Tom Spalding.
  • In January 2000, 2Wire delivered its first product, the HomePortal residential gateway, at that year's CES.
This broadband modem/router combination enabled DSL connectivity with home networking, firewall protection, and
remote management capabilities. The following year, in January 2001, 2Wire delivered a wireless residential gateway.
  • In 2002, the company created a remote customer premises management platform called CMS. Later that year, 2Wire
published the Open Gateway Management Protocol (OGMP).
The OGMP formed the basis for the TR-069 WAN management protocol subsequently ratified by the DSL Forum in 2004.
  • In early 2003, 2Wire delivered a wireless gateway with a complete system-on-a-chip (SoC) architecture.
Also in 2003, the company acquired Sugar Media, a digital media provider.
  • The following year, in the spring of 2004, 2Wire launched MediaPortal, a multi-service media platform that integrates
DSL and satellite services. The MediaPortal-powered set-top box, combining television, digital video recorder, video,
music, photo viewings, and messaging capabilities, was deployed by AT&T in 2006 as part of its Homezone service.
  • In January 2006, 2Wire introduced the HomePortal intelligent Network Interface Device (iNID), an outdoor
broadband residential gateway that supports VDSL2 and fiber to the premises (FTTP) connections.
  • 2Wire acquired Kenati Technologies, an embedded device software company, in October 2007. In June 2008,
2Wire had shipped more than 20 million residential gateways to its telecommunications provider customers.
  • In November 2008, 2Wire and Blockbuster Inc. developed and released MediaPoint Digital Media Player,
a set-top box that plays video content from a home computer network.

Products[edit]

  • 2Wire produces a series of residential gateways under the HomePortal name that enable home networking
with interfaces that range from ADSL2+ to fiber to the node (FTTN) (VDSL 1 and 2), as well as FTTP.
The gateways are based on integrated system-on-a-chip architectures, and have native TR-069 support, as
well as support for HomePNA, MoCA, USB, 802.11b/g/n wireless standards, and Web-based remote access.
  • The company also produces MediaPortal, a multi-service media platform that combines high-definition (HD)
and standard-definition (SD) broadcast satellite or off-air TV programming with broadband services,
Digital video recorder (DVR) capabilities, music and photo storage and sharing, and home networking.
  • One of their gateways, the 2701, had issues with the power supply, prompting Bell Canada to proactively
swap the power supplies to their customers in 2008. Some laptops with two types of Intel wireless
adaptors exhibited wireless issues, which were fixed by an updated Intel device driver.
  • The Pace 5012NV-002 Gateways were only available in Singapore for SingTel exStream Fiber Service
and 2Wire 2701HG-B Series. The rest of the world, the brand is 2Wire.

The family of TriMedia TM32 CPUs[edit]

2Wire uses own-branded CPUs in most models of its broadband access equipment.

These CPUs contain the TriMedia VLIW (Very Long Instruction Word) core.
The TriMedia is a scantly documented CPU core. (TriMedia timeline taken from )

The 2Wire Medusa, the 2Wire Perseus and the 2Wire Ares CPUs all contain the TriMedia TM32 core.

The TM32 is the same TriMedia core found in the Trident (was Nexperia / NXP, was Philips)
NXP PNX15xx family of VLIW processors. (The Philips / NXP PNX CPU roadmap)

The key difference between the CPUs in the NXP PNX15xx series is the speed grading.

This ranges from a maximum core speed of 240MHz for the NXP PNX1500,
through 266MHz for the NXP PNX1501 and up to 300MHz for the NXP PNX1502.

The 2Wire Perseus and the Ares processors have DDR (double data rate)

memory systems supporting memory bus speeds of up to 200MHz (DDR-400).

Whereas, the Medusa CPU, found in the 2Wire 1800 models, supports only single data rates.

Consequently, it can be compared to Philips’ earlier NXP PNX13xx series.

The NXP PNX13xx family offers core speeds of up to 200MHz and maximum SDRAM speeds of 183MHz.

The NXP PNX1302 is the top of the range in this series.

Since these processors all share the TM3260 instruction set, binary code should be largely portable

between them, although in terms of the peripherals they control, they are likely to be incompatible.

  • The “U-Verse” 2Wire 3801HGV VDSL2 Modem-Router, supplied by AT&T is driven by a Denali.

This one is branded as a Broadcom BCM6091KPBG (another dual core TriMedia TM32).
One curiosity is an anomaly in external hardware clocking of the 2Wire.
The reference designs for the TM1500 series all use a 27MHz crystal oscillator.
The CPU then uses a multiplier to generate a 1.728GHz internal clock.
Dividers are used to derive the frequencies needed to drive internal modules.
This clock division is fine-tuned to a precision of just 0.4Hz using a handful of registers.
By contrast, instead of using the reference 27MHz crystal, the 2Wire 27xx boards use 28MHz crystals.
The VDSL2 3800HGV board also uses a single TM32 core Ares CPU clocked at 28MHz. However, 2Wire’s
most recent VDSL2 board, the 2Wire 3801HGV which runs on a dual TM32, is clocked externally at 25MHz.

  • Below is the NXP Nexperia PNX1501. The NXP PNX1501, a 266MHz TM32 core
