| FTTH |
| The leading FTTH technology is PON or Passive Optical Network technology. This approach differs from most of the telecommunications networks in place today by featuring "passive" operation. Active networks like DSL, VDSL and cable have active components in the network backbone equipment, in the central office, in the neighborhood network infrastructure, and in the customer premises equipment. PONs have only passive light transmission components in the neighborhood infrastructure with active components only in the central office and the customer premises equipment. |

| GPON |
|
Gigabit Passive Optical Networks (GPON) provides a capacity boosts in both the total bandwidth and bandwidth efficiency through the use of larger, variable-length packets in PON technology. GPON is standardized in ITU-T G.984 (GPON) that permits several choices of bit rate, but the industry has converged on 2.488 Gbps of downstream bandwidth, and 1.244 Gbps of upstream bandwidth [1]. GPON Encapsulation Method (GEM) allows very efficient packaging of user traffic, with frame segmentation to allow for higher QoS for delay-sensitive traffic such as voice and video communications.
The beneficial features of GPON based upon requirements set forth by service providers are as follows [2]:
- Full Service Support, including voice (TDM), Ethernet, ATM, leased lines, and others
- Physical reach of at least 20 km with a logical reach support within the protocol of 60 km
- Support for various bit rate options using the same protocol, including symmetrical 622 Mbps, symmetrical 1.25 Gbps, 2.5 Gbps downstream, 1.25 Gbps upstream, and others
- Strong Operations, Administration, Maintenance, and Provisioning (OAM&P) capabilities offering end-to-end service management
- Security at the protocol level for downstream traffic due to the multicast nature of PON

| GSM & WIRELESS DOMAIN |
|
GSM (Global System for Mobile Communications) is the world's most popular wireless phone technology. It's used by more than one billion people around the world.
At AT&T, we offer a nationwide GSM/GPRS footprint across 100 percent of our service area.
Benefits
GSM’s offers unparalleled global roaming capabilities, as well as the truest voice quality in wireless. Its easy-to-use data capabilities offer service up to the fastest wireless broadband service currently possible.
Prevalence
There are several technologies companies use to provide wireless services. While there may never be one standard technology worldwide, GSM is viewed as a global technology used by more than 600 carriers in 200 countries. Roaming agreements among these carriers allow GSM customers to use their phone when traveling in most countries around the world.
Levels of Service
GPRS
GPRS (General Packet Radio Service) is the first level of data service on GSM. This packet-based service utilizes the GSM Radio Access Network, combined with a core network dedicated to data. With average speeds of about 35 kbps, GPRS allows nationwide text and email service and basic WAP (Wireless Application Protocol) Internet browsing. GPRS is the service of choice for many text messaging PDAs, including Blackberry, Treo, and others.
EDGE
Further enhancements in data capability over the GSM network are provided with EDGE service (Enhanced Data rates for GSM Evolution). With typical speeds of 75 to 135 kbps, advanced mobile services like video and music clips, full picture & video messaging, high-speed color Internet access, and email on the move are possible. EDGE is especially important to business users as it permits mobile access to corporate applications at speeds far in excess of dialup. True wireless broadband service is being deployed in both GSM and CDMA worlds, but AT&T’s existing nationwide offering of EDGE/Wi-Fi service makes corporate users truly mobile using either a wireless-enabled Windows Mobile device, or any of a host of other new devices.
UMTS
UMTS (Universal Mobile Telephone Service) is the next level of service. It is the leading 3G technology choice today, offering potential worldwide coverage. Typical speeds of 220 to 320 kbps permit workgroup collaboration, vertical-specific devices (an x-ray viewer, for example), video and music on-demand, digital TV and radio, and services such as home or business security video monitoring.
HSDPA
Enhancement of UMTS with HSDPA (High Speed Downlink Packet Access) moves GSM into the range of true broadband service. With typical speeds in the range of 400 to 700 kbps, and a burst mode of up to several megabits per second, it is the fastest available cellular broadband technology. This brings a mobile data experience that is essentially the same experience of a wired network in the home or office.
Additionally, unlike other wireless technologies, UMTS and HSDPA offer you the ability to make simultaneous voice and data calls. This flexibility lets you use the same phone to speak with someone while also accessing Internet information.

| IT & IP TELEPHONY |

IP Telephony VoIP
IP telephony (Internet Protocol telephony) is a technology that uses Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN ).
Definitions
Convergence refers to the coming together of data, voice and video, i.e. the ability to carry all
media types on one network. This is what IP enables. A converged network does not see any
difference between voice and other media types; once digitized, voice is just another data stream.
Voice over IP (VoIP) indicates that an analog voice signal has been digitised and converted into the packet format used by IP. This is done in order to allow telephony and other audio signals to be transported over the same network as regular data traffic. A separate network normally carries
Telephony: either the public infrastructure or the internal network of regular phones connected to
The company’s PABX. Thus, VoIP refers to a conversion and transportation process. The key benefit Is the use of one network instead of two.
Internet Telephony refers to VoIP over the public Internet. Although technically feasible, the call
quality is considered to be too variable for serious use by business professionals. This comes from the fact that voice traffic has to be given priority over data. However, VoIP is employed over
managed IP infrastructures, e.g. corporate intranets and the backbone networks of carriers.
Unfortunately, the terms VoIP, Internet Telephony and IP Telephony are often used interchangeably.
IP Telephony it refers to the telephony applications that are enabled in a homogeneous IP environment as well as the integration of these applications with mainstream business processes. IP Telephony therefore focuses on: the business case; the end user experience; the increase in productivity that comes via the ease with which telephony applications such as call conferencing can be employed; and finally and all importantly its impact on the all-important bottom line.
