1. DS1/T1
(1.544Mbps)
A DS1 (also known as a T1) is a dedicated
phone connection supporting data rates up to 1.544Mb/sec. A DS1/T1
line actually consists of 24 individual channels, each of which
supports 64Kbits per second. Each 64Kb/sec channel can be configured
to carry voice or data traffic.
Pacific
Bell's FasTrak Flexible DS1 - Provides different speeds for
different data transmission requirements. FasTrak Flexible DS1
is available in increments of 256, 384, 512, or 768Kbps, or 1.544Mbps.
The FasTrak Flexible (fractional)
DS1 works in the same way as does a full DS1/T1, but only a portion
of the 24 channels is available. For 128 Kbps Fractional DS1,
two of the 64 Kbps channels are available (2 x 64 = 128). For
256 Kbps service, four channels are available (4 x 64 = 256),
and Fractional DS1 at 384 Kbps uses six of the 64 Kbps channels
(6 x 64 = 384).
With FasTrak Flexible DS1, you can
enjoy DS1 digital service at a minimum capacity and grow to the
full 1.544Mbps as your network grows or as your needs change,
choosing increments of multiple DS0 level channels that meet your
bandwidth needs.
Performance Features:
- Extended super-frame format framing (ESF)
and B8ZS line coding enable us to actually survey your circuits'
performance while they're being used.
- Contiguous routing ensures that every part
of a message transmitted via Flexible DS1 will arrive simultaneously
through the same circuit.
FasTrak High-Capacity
DS1 - Pacific Bell FasTrak HiCap DS1 (T1) is a dedicated, point-to-point
private-line service that operates as a full duplex digital channel
at 1.544Mbps. Larger offices with high bandwidth needs are the best
candidates for a the FasTrak High-Capacity DS1 service.
2. DS3/T3
(45Mbps)
Pacific Bell FasTrak
HiCap DS3 (T3) is a fiber optic, dedicated, point-to-point
private-line service that operates as a full duplex digital
channel at 45 Mbps. DS3's allow businesses to move data or voice
traffic efficiently for a fixed monthly rate. Service is available
in a basic (full 45 Mbps) or a channelized (28 multiplexed digital
channels - 1.5 Mbps each) format.

Data Base Access
FasTrakSM Primary Rate ISDN provides
24 individually controlled, software-defined channels for all
of your voice and data communications. Each channel has a 64Kbps
capacity, enabling a total transmission speed of up to 1.536Mbps.
Primary Rate ISDN is served over a DS1 or DS3 transport facility
for flexibility and scalability. Out-of-band signaling allows
you to carry 20% - 30% more traffic than analog trunks. And call
setup is a quick half a second, compared to 3-5 seconds for analog
trunks, for extra efficiency.
With Primary Rate ISDN, you can predefine
the number of channels used for specific types of calls. So whether
it's voice, data, or video, Primary Rate ISDN can help maximize
your network's efficiency. And it includes Caller ID at no additional
charge.
Applications:
-
Internet and networks connections
-
Video
-
LAN/WAN interconnectivity
-
EDI
-
High-resolution imaging
-
Private line backup
-
Telecommuting host access
-
Station Record Detail
gives you the option of departmentalized billing, which allows
greater cost control.
-
Deluxe Call Transfer allows
you to transfer a call to any telephone, anywhere, to free up
the PRI line for other calls.
-
Inform 911 sends emergency
dispatch operators detailed call information so they can send
help to your specific location.
-
PRI Subgroups allow you
to customize your network by defining the types of calls and
call volume for their company
-

5. ATM
Pacific Bell's FasTrak Asynchronous Transfer
Mode (ATM) Cell Relay Service* is a high-speed, packet-switched
transport service designed for unifying diverse traffic (data,
image, voice, video) over common facilities in fixed length
cells. This enables users to consolidate currently diverse networks.
FasTrak ATM is well suited for real-time, delay-sensitive, broadband
applications such as multimedia, real-time workgroup computing,
and imaging. With transmission speed ranging from 1.544 to 155Mbps,
FasTrak ATM Cell Relay Service* also helps eliminate congestion
and delays on extended networks.
Along with increased bandwidth and flexibility,
the benefits of multiservice networking include decreased cost
and complexity, and the faster adoption of new services and
applications.
Applications:
-
Multimedia combining voice,
video, text, and image
-
ADSL integration for high-speed
remote LAN and internet access
-
-
High-resolution videoconferencing
and streaming video
-
Workgroup and collaborative
computing
ATM uses Fast Packet Technology,
provides bandwidth (up to 155Mbps) and flexibility to handle your
enterprise networking needs into the future.
Features and Primary Uses:
- Ability to integrate LANS and WANS
- Handle real-time sensitive traffic
- Affordable high-speed bandwidth (45Mbps to
155Mbps)
- Supports voice, video, data, and multimedia
traffic on the same network
- Connectivity to Frame Relay Circuits
ISDN:
Pacific Bell's Business Integrated
Services Digital Network is a fully digital network access service
that integrates voice and data over standard copper telephone
wiring. Users can perform two activities at once (voice and fax,
data and fax, data and voice), or use both channels for the same
data application (Point to Point Protocol "bonding" to obtain
a total throughput of 128Kbps). It helps workers increase productivity
by offering exceptional flexibility and multitasking capabilities.
Based on international standards,
established by the International Telephone Union (ITU, formerly
CCITT), Business ISDN can connect to other BRI ISDN services anywhere
in the world, allowing fully digital end-to-end connections.
A user of Business ISDN has access
to the Public Switched Telephone Network (PSTN). They can make
or receive voice calls to any telephone line, whether it?s ISDN
or not. Multiple applications may reside at the same site (web
browsing and videoconferencing) because ISDN can place data calls
to any other ISDN site.
Business ISDN also includes several
calling services free of charge
-
Hold
-
Consultation Hold
-
Three-Way Conference
-
Call Transfer
