Product Overview ATM is a way to transmit information. It can handle voice, data, and video through a single network circuit. ATM offers you the fastest speeds available, and it's flexible enough to meet your specific needs. ATM is currently available at speeds between 1.5 Mbps and 155 Mbps -- roughly 70 times the capacity of a DS1. In the future, ATM is targeted to reach 1 gigabit (1 billion bits) per second. Because ATM transmits voice, data, and video, you no longer need separate dedicated lines for different types of traffic. ATM's flexibility means you can integrate it easily with your current network. You determine your own bandwidth and access needs, now and in the future. And, you never pay for what you don't use. Product Overview Businesses that require flexibility for use of diverse applications like personal computers, fax machines or video can look to BRI for superior performance compared to an analogue dial-up line. Telecommuting and the ability to access the Internet are simple and efficient with BRI. Business people who want the flexibility of working from home combined with the efficiency of working at the office can use BRI for the best of both worlds. One of the two 64kbps channels can be used for a regular phone line, and the other can be used for a personal computer to LAN connection. Efficiently accessing Internet Web sites filled with graphics requires a higher bandwidth than what is available through phone lines that use analogue modems. With BRI, customers can enjoy speeds that are up to 10 time faster. 64kbps or 128kbps speeds with one BRI service -- at a price much lower than dedicated data access service. A Phone line and a 64kbps data line in one service charge Access to most cities in Alberta (where distance to a TELUS CO supporting ISDN is within acceptable parameters) Dial access to many other BRI locations in North America Dial-up LAN to LAN at 128kbps speeds for short duration links Higher Speeds (T1 - 1,44Mbps) if you use inverse Muxing to combine Multiple ISDN lines Flexibility -- allowing users and IT Managers to tailor Connections to various locations at LAN or other link speeds by using different numbers of ISDN lines at different times. Disaster Recovery linking to support sites or Back-up Data with Dial flexibility and ISDN speed options. Tariff Reference Terms and Conditions Rates Carrier Access Tariff Item 485 Benefits and Applications Customers who are sophisticated users of telecommunications for diverse applications and employ the use of PCs, fax machines, or video will be attracted to BRI. BRI will also appeal to customers whose need to send data is growing (both in frequency and in the size of the files to be sent). More and more users want to be able to send pictures, images and facsimiles simultaneously while talking on the phone; share computers, printers, databases; or bridge LANs. In general, they are looking for more efficient and cost effective access with broader capabilities. They want a platform to build applications and improve the way they do business. Prime applications for BRI service include: Internet Access Telecommuting Video Conferencing LAN to LAN Product Overview Intentionally Left Blank Benefits and Applications Intentionally Left Blank Product Overview DNA provides customers with contiguous bandwidth from the customer's Connection Point to the Serving Central Office. Tariff Reference Terms and Conditions Rates Carrier Access Tariff Item 500 Benefits and Applications Digital Network Access service (including Fractional DNA Access): DNA provides high quality, local access from a customer's premise to a TELUS central office. It provides local digital connectivity to support a customer's voice, data & image/video requirements. Provides local connectivity to national digital services: Hyperstream Megaplan Product Overview The TELUS Frame Relay Service is digital technology that provides high-speed data transmission. It is an ideal solution for end-user customers who need to exchange data with remote sites quickly, economically, and simply. TELUS Frame Relay is a wide area data networking service intended to support a wide array of bursty data applications, including LAN-to-LAN, and LAN-to-HOST interconnections at a variety of Service Connection (Port) speeds in DS-0 increments from 56 Kbps to 1.5 Mbps. TELUS Frame Relay Service is a cost-effective solution because it relies on the public network. Only one connection is required for transmission. In contrast, a private network requires several dedicated lines. Since your customer's data travels over the TELUS digital network, access to the full bandwidth of the network is also available if needed. Tariff Reference Terms and Conditions Rates Carrier Access Tariff Item 501 Benefits and Applications Frame Relay Service: Is available in over 1500 locations in Canada (through HyperStream NNI when available). Is a cost effective network compared to a private dedicated solution. Offers a quick response time, higher bandwidth and low delay. Has access speeds of 56 Kbps to 1.5 Mbps are available to meet application requirements for bandwidth, response time and growth. Has meshed PVC connectivity that simplifies the design of virtual networks and allows customers to focus on access location requirements and user satisfaction. A choice of Quality of Service (QoS) ensures the operational performance of the customer's network meets their business needs. Product Overview The Primary Rate Integrated network is a DS-1 based digital local access service with the ISDN PRI interface standard between the customer's CPE and the central office switch. It allows integrated access of the PSTN, Inbound and Outbound LD services plus Virtual Private Network service. PRI supports voice, data and image applications at 64 kbps per DS-0 channel up to DS-1 (1.544 mbps) speed. PRI Standard supported by TELUS: NI-1 and NI-2 for DMS switching office, NI-2 for GTD5 and 5ESS switching offices. PRI access loop uses Clear Channel/Out-of-band signaling technology: ESF for framing, and B8ZS for line code. Standard Single D Channel Controlled PRI System Group: The first initial DS-1 contains 23 B channels (information channels) plus one D channel (Signaling channel). Subsequent PRI's can each can have 24 B channels. All TELUS PRI switches support Single D Channel Controlled PRI System Groups with up to 20 DS-1s. A single D Channel Controlled PRI System Group can have the option of a "backup D channel" at the second DS-1 span. Multiple D Channel Controlled PRI System Group: TELUS also supports a PRI System Group that requires a single D channel controlled sub-DS-1 group or multiple DS-1's each with a single D channel inter-working together as one PRI System Group. PRI is the most cost-effective digital local access service for customers who require multiple local access loops for different types of incoming, outgoing or two-way voice or data calls. Tariff Reference Terms and Conditions Rates Carrier Access Tariff Item 495 Benefits and Applications Lower Hardware Cost for PBX Customers: Digital DS-1 Trunk Cards in most cases are more economical and can replace multiple Analog Trunk Cards. Fewer PSTN Charges: The call-by-call feature of Megalink allows the customer to use fewer PSTN access connections as compared to analog and DEA services. Lower LD Charges for High Volume Data Calls: At 64 kbps plus split second call set-up, call completion is many times faster than calls at modem speed, therefore allowing customers to reduce their LD charges significantly. At 64 kbps per channel (DS-0) speed or multiple of DS-0, applications such as high quality videoconferencing at 128 kbps or 384 kbps becomes more cost-effective for business customers. Calling Line ID Feature of PRI: Allows customers to integrate an incoming call with a customer or product information display on a computer terminal for smart call answering service. Dialed Number Identification Service (DNIS): The dialed digits originated by a caller are provided automatically as part of the call set-up message. This capability enables incoming call centres to manage the call answering service efficiently. Answer Supervision Information: The PRI call connect message information will enable customers to have an accurate call detail record (SMDR) for internal cost allocation or client billing purposes. Speed: Split-second call set-up time enhances productivity for outbound call centre customers. It also helps to reduce LD charges for high volume outbound calls. Security: CLID enables business customers to screen or track incoming calls for security purposes. Survivability: PRI is a proven robust switched digital service. If further survivability is required by customers, they may subscribe to PRI's advanced features which include a back-up D channel, Call Forward Busy, Access/Central Office Diversity etc.
