to dynamically assign an IP address to the device. Because of this capability, the
Pipeline 25Px/75Px can be used for standard consumer Internet access accounts,
which are considerably less expensive than business or local area network (LAN)
accounts.
NOTE:
For the most complete information about using the 2B Data feature, see
the
Data/Video Reference.
In this guide, “Digital Data Calls” on page 200
includes details about how the system functions with digital
communications devices.
The Pipeline 25Px/75Px makes outgoing calls only; it cannot perform server-side
applications.
The Pipeline 25Px/75Px connects to the network card in a PC; the access device
connects to an MLX extension jack that can access a PRI, T1 Switched 56, or BRI
facility using Automatic Route Selection (ARS, Hybrid/PBX mode only)
programmed to route data calls over appropriate facilities, personal lines, or dial
access to pools (not recommended). The Pipeline 25Px/75Px can use the
system’s 2B Data feature, for speeds as high as 128 or 112 kbps.
The access device can also be used in applications that require a user to dial into
a server located on a remote LAN, for example, at a branch site accessing
information on a service on the main-site LAN. The far-end device (in this
example, at the main site) must be able to terminate a digital connection and
establish a connection with the Pipeline 25Px/75Px using industry-standard
Point-to-Point Protocol (PPP) and/or Multichannel PPP. Examples of such far-end
devices are remote-node LAN access servers such as those used by Internet
service providers and ISDN routers capable of answering incoming calls.
The Ascend Pipeline 25Px/75Px includes the following components:
■ Pipeline 25Px/75Px, model P25/75-1S-PX
■ 10Base-T Ethernet crossover cable for connecting the access device to the
network card in a user’s PC
■ RJ-38C ISDN cable for connecting the access device to the MLX jack on
the system
■ DB-9 to DB-25 serial cable adapter for use when connecting the Pipeline
25Px/75Px control port to a PC serial port
■ Power supply
Considerations and Constraints 67
One Pipeline 25Px/75Px serves a single PC; it cannot serve multiple PCs or other
terminal equipment such as fax machines or telephones. For 2B data, it requires
both extensions of an MLX extension jack.
