UNDERSTANDING FRAME RELAY
Frame relay is a wide area network (WAN) service designed to
minimize physical connections. This is accomplished by using
virtual connections within the frame relay cloud and accessing
these virtual circuits with normally one physical connection at
each location to the frame relay service. Virtual circuits are
addressed using header information at the beginning of each
frame. These frames are formatted by the user's CPE equipment
such as the ADTRAN FSU.
Chapter 1. Introduction
Chapter 1
Introduction
ANSI standards describe how each frame must be constructed to
provide interoperability between CPE equipment and frame
relay switching equipment. Each frame must contain a header,
at least one byte of information data, two bytes of CRC16, and a
trailing flag 0x7E.
This header information contains a virtual circuit address known
as a DLCI (data link connection identifier). The header information also contains bits used for network congestion control.
Frame relay virtual circuits may be defined as permanent (PVC)
or switched (SVC). PVCs have the same DLCI for a given path
each time a user protocol session is established. The network
service provider assigns these DLCIs at subscription time. SVCs,
on the other hand, have DLCIs dynamically assigned each time a
user protocol session is established. The CPE equipment must
request a call and the DLCI is assigned by the network switching
61200.130L1-1 FSU User Manual 1
Chapter 1. Introduction
equipment. This DLCI is valid until the call is disconnected and
may be assigned a different value each time a call is requested.
PRODUCT OVERVIEW
The FSU provides a low cost solution for the CPE equipment in a
private or public frame relay network. The FSU connects to the
frame relay network via 56/64k DDS (digital data service) or
T1/FT1 access links. Connections to 56/64k DDS are made
using an integral 56/64k DSU or an external DSU. T1/FT1
connections are made using an external T1 DSU/CSU through a
V.35 interface.
The FSU provides connections to the user equipment through
two independent ports emulating a DCE device. These ports can
be configured for either RS-232 or V.35 signal specifications.
Synchronous protocol speeds up to 512 kbps and asynchronous
protocol speeds up to 38.4 kbps are supported.
The FSU handles each frame of the user data in a three-step
manner. The first step is terminating the user protocol. The
layer at which this termination occurs varies depending on the
user protocol selection for a given port. The next step is examining the user protocol destination address and routing to the
destination port and virtual circuit. The last step involves
encapsulating the information field of each frame and reencapsulating based on the destination port configuration. A
similar process is used for frame relay frames received on the
network port.
The major features of the FSU are as follows:
• Two DTE (data terminal equipment) ports for use on a single
frame relay network interface.
• Support for IP (internet protocol), SDLC (synchronous data
link control), Bisync, SLIP (serial link IP), PPP (point-to-point
protocol) both sync and async, frame relay, BOP (bit-oriented
protocol), and async protocols.
• SNMP (simple network management protocol) management
capability provided inband with support for RFC 1315 (frame
2 FSU User Manual 61200.130L1-1
relay DTE MIB), RFC 1213 (MIB II), and ADTRAN Enterprise
MIB.
• DCE port supporting rates of up to 512 kbps.
• Optional integrated 56/64 DDS DSU/CSU.
• Telnet-provided remote terminal management control.
• FLASH code space for easy software upgrades.
DDS OPERATION
DDS is a nationwide service that allows interconnection and
transportation of data at speeds up to 64 kbps. The local exchange carriers provide the local loop service to DDS customers
and may provide data for routing Inter-LATA to an
interexchange carrier. With the optional integrated 56/64 DDS
DSU, the FSU supports the 56/64 kbps DDS service rate yielding
DTE rates of 2.4, 4.8, 9.6, 19.2, 38.4, 56, and 64 kbps.
56/64K DDS DSU OPTION
The FSU is available with an optional integrated 56/64k DSU
(part number 1200130L2). This gives the unit the ability to
directly connect to a frame relay network via a 56 or 64k DDS
circuit.
Chapter 1. Introduction
SNMP MANAGEMENT
SNMP management capability is provided inband with support
for RFC 1315 (frame relay DTE MIB), RFC 1213 (MIB II), and
ADTRAN Enterprise MIB. Telnet capability is also supported.
For non-SNMP environments, VT 100 and front panel operation
is supported.
