The Z-Edge 64 is a compact integrated access device (IAD) that provides
Internet Protocol (IP) routing features as well as traditional voice services
over a single Di gital Subsc ribe r Line (DSL) WAN connection. The Z-Edge 64
BH2A offers Integrated Services Digital Network Basic Rate Interface (ISDN
BRI) voice transport. The Z-Edge 64 H2A supports Plain Old Te lephone
Service (POT S ).
Figure 1: The Z-Edge 64
In a traditional Voice over DSL (VoDSL) architecture, the Z-Edge 64 can
operate with a Digital Loop Carrier (DLC), like the Zhone Multi-Access Loop
Concentrator (MALC), or a voice gateway, such as a Zhone Sechtor 100A.
Figure 2 shows an example application for the Z-Edge 64.

The Z-Edge 64 has the following featur es:
• T oll-quality voice support with c ustom calling features
• Internet Protocol (IP) routing
• Network Address T ranslation (NAT) capabilities
• Dynamic Host Configuration Protocol (DHCP) server/client functionality
• Simple Network Management Protoco l (SNMP) manageability
Protocols and technologies
The Z-Edge 64 supports the followi ng networking protocols a nd technologies.
You should have an understanding of these concepts before operating the
Z-Edge 64:
ATM
Asynchronous Transfer Mode (ATM ) is a cell-based, high-speed networking
technology. The ATM cell has a fixed length of 53 bytes. The cell is broken
into two parts, the header and the payloa d. The header (5 bytes) contains the
14 Z-Edge 64 Configuration Guide
DSL
Protocols and technologies
addressing information, and the payload (48 bytes) carries the voice or data
message. Since each ATM cell has its own addressing mechanism, the cells
can be sent asynchronously, or in any order.
ATM uses virtual channels (VCs) and virtual paths (VPs) to route cells in an
ATM network. A VC, identified by a virtual channel identifier (VCI) is a
connection between two communic ating ATM entities. A VC consists of a
concatenation of one or more ATM links. A VC provides a certain quality of
service, which is defined in t he ATM Traffic Descri ptor. A VP, identified by a
virtual path identi fier (VPI), is a group of VCs between two ATM endpoints.
A physical link can support many VPs. Similarly, a VP can contain many
VCs.
Digital Subscr iber Line (DSL) t echnol ogies pr ovide access to high- bandwidt h
networks over a unshielded twisted pair (UTP) of copper wires. By using
frequencies above the te lephone bandwidth (300Hz to 3,200Hz), DSL can
encode more data to achieve higher data rates than would otherwise be
possible in the restric ted frequency range of a POTS network. The DSL
family includes several variations.
NAT
Symmetric Digital Subscr iber Line (SDSL) provides data-only symmetric
transfer rate s of up t o 2.32Mbps over a si ngle pa ir of cop per wire s. SDSL uses
the same 2B + 1Q si gnaling as I SDN. SDSL servi ce requir es t hat the customer
is no further than 10,000 feet from the central office. SDSL is defined in ITU
G.991.1.
Global Symmetric High-bit-rate Digital Subscriber Line (G.SHDSL) is
designed to operate with both HDSL and SDSL networks. G.SHDSL extends
the reach and transfe r rates of DSL servic es. G.SHDSL supports adaptive data
transfer rates of 192Kbps to 2.3Mbps with a reach of over 20,000 f eet. The
G.SHDSL specification (ITU standard G.991.2) allows for transmission over
single-pair and two- pair copper wires.
Network Address T ranslation (NAT) is an Internet standard that enables a
local area n etwork (LAN) to use one set of IP a ddress es for internal tra ffic and
a second set of addresses for external traffic. Hosts in a private network c an
transparently access an external network and enable access to selective local
hosts from the outside.
A NAT device connecting the public Internet and the network it serves
rewrites IP addresses and port numbers in IP headers. The packets appear to
be coming from a single public IP address of the NAT device, instead of the
actual source or destin at ion.
NAT serves two main purposes: It provides a type of firewall by hiding
internal IP addresses, and it enables a company to define more internal IP
Z-Edge 64 Configuration Guide 15
Features and capabilities
DHCP
addresses. Since the addresses are used internally only, there is no possibility
of conflict with IP addresses used by other companies and organizations.
The Dynamic Host Control Protocol (DHCP) provides a mechanism through
which client computers using TCP/I P can obtain configuration parameters
(such as the default router and the Domain Name System [DNS] ser ver,
subnet mask, gate way addre ss, a nd lease time) fr om a ce ntrally lo cated DHCP
server. DHCP dynamic rec onfiguration requires a DHCP server , a forwarding
agent in each router, and DHCP capability in each client TCP/IP stack. The
most important configuration parameter carried by DHCP is the IP address.
Dynamic addressin g allows a device to have a different IP address every time
it connects to the network, and in some systems, the device IP address can
change while it i s still c onnec ted to the ne twork. DHCP also suppo rts a mix of
static and dynamic IP addresses.

BAN
A DHCP client is an Internet host using DHCP to obtain confi guration
parameters such as a network address. A DHCP server is an Internet host that
returns configur ation parameters to DHCP clients. As a DHCP client, the
Z-Edge 64 receives its IP address and configurati on parameters fr om a DHCP
server, such as the BAN.
RIP
16 Z-Edge 64 Configuration Guide
Routing Information Protocol (RIP) is widely used for routing traffic on the
Internet and is an interi or gate way protocol (IGP), which means that it
performs routing withi n a single autonomous system. RIP is based on
SNMP
Protocols and technologies
distance-vector algorithms that measure the shortest path between two points
on a network, based on the addresses of the originating and destination
devices. The shortest path is determine d by the number of hops between those
points. RIP routers maintain only the best route (the route with the lowest
metric value) to a destinat ion. After updating its routing table, the router
immediately begins transmitting routing updates to inform other network
routers of the shortest r oute.
Routing Information Protocol version 2 (RIPv2) is the latest enhancement to
RIP. RIPv2 allows more information to be included in RIP packets and
provides an authentication mechanism.
Z-Edge 64 users ca n manage their system with Simpl e Network Management
Protocol (SNMP) software. SNMP is based on network management stations
(managers) and network managed elements ( agents). SNMP allows network
managers and network agents to communic ate.
There are three types of SNMP transactions—a Get, a Set, or a Trap. The Get
and Set commands are sent from the manager to the agent to determine (Get)
or configure (Se t) network variables and st atus. A Trap is an e xception to this
SNMP transaction patter n, in tha t the Trap is an unsolicited event report sent
from the agent to the ma na ger. When the SNM P m an ag er re cei ves the Trap
message, it can be stored in the Management Information Base (MIB) and
displayed on a terminal screen.
A MIB is a virtual database that identi fi es each manageable object by name,
syntax, accessibility, status, a text description, and a unique
manageable-Object I dentification number (OID). MIBs come in three
varieties: Public , Expe rimental, and Private Enterprise .
Automatic rate adaption
Automatic baud rate de tection (also known as rate adaption) allows receiving
devices to communicate with transmitting devices operating at different
speeds without the need to est ablish data rates in advance . By determini ng the
baud rate from the tra nsmitti ng device, the receiv ing Z-Edge 64 automatica lly
trains to match the line rate of the incoming da ta.
Usually the re is one centr al office (CO) device transmi tting to many customer
premises equipment (CPE) units. When a CO device trains with a CPE unit,
the devices will settle on the lower of the two devices’ line rates. It is optimal
to set the CPE line rate to 2320 kbps because it allows a wide range of rates
for CO and CPE devices to agree upon.
The training of line rates is faster on G.SHDSL than on SDSL. The G.SHDSL
rate adaption process occurs during the CO and CPE modems’ handshake,
where the devices probe the G.SHDSL line to find the best possible line rate.
The SDSL autobaud process is slower because the CO and CPE modems use
an algorithm to step through a sequenc e of line rates, where the devices

Features and capabilities
Physical interfaces
establish a connecti on at each line rate and then move to the next higher rate
until they r each the f inal rate, which is the lowe r of the l ine r ates. Note t hat the
Z-Edge 64 does not currently support SDSL autobaud.
The Z-Edge 64 has following physical inte rfaces:
• WAN: One RJ11 port.
A standard RJ1 1 port connects un shielde d twis ted pair (UTP ) copper wir e
to DSL networks.
• LAN: One 10/100BaseT RJ45 port.
A RJ45 port carries both management and data traffic, and interconnects
with most Tr ansfer Control Protocol/I nternet Protocol (TCP/IP) hubs and
networks.
• Phone lines:
Z-Edge 64 BH2A: Four ISO 8877 ports support ISDN BRI.
or
Z-Edge 64 H2A: Four RJ11 ports support POTS.
• Serial: One DB9 port.
A single DB9 asynchronous serial port provides direct PC or virtual
terminal (such as VT100) acces s to the Z-Edge 64. The serial port allows
access to the CLI.

18 Z-Edge 64 Configuration Guide
The Z-Edge 64 provides the following physic al interfaces to configu re the
unit:
• Serial (craft)—An out-of-band RS232 serial interface
• Ethernet—A 10/100Base-T RJ45 port
SNMP
Managing the Z-Edge 64
You can configure the Z-Edge 64 using any of the following methods:
• Simple Network Management Protoco l (SNMP)
• Command Line Interface (CLI)
• Zhone Management System (ZMS)
The Z-Edge 64 supports SNMP version 1 and version 2 for system
management. Network object variables are MIB-II compliant.
SNMP can be accessed over IP interfaces or the Ethernet interface. The
SNMP agent on the Z-Edge 64 u ses port 1 61 of us er data gra m protocol (UDP)
for management traff ic and UDP port 162 for error events and SNMP traps.
The MIBs for the Z-Edge 64 control the following:
• Data port configuration, status, and diagnostics
• General system management, field upgrades, and alarms
CLI
ZMS
• Traps
The CLI is functionally simila r to SNMP . The CLI commands are equivalent
to SNMP get and set commands and allow you to configure the unit. The
interface is accessible both using telnet and through a local serial port. You
can configu re the sam e elements with the CLI as you can w ith SN M P.
ZMS allows Z-Edge 64 users to navigate, monitor, and manage their Zhone
networks with a graphical use r interface.

System security
There are several methods to guard against unauthorized access to your
Z-Edge 64, such as changing the default user password. You can also set up
SNMP access lists to re stric t acc ess to your syst em. See SNMP adminis tration
in Chapter 7 for mo re in fo rm at ion ab out se t ting SN MP acce ss lis ts.
Changing the default user password
When adding us ers, t he syst em a utomatic ally assigns a tempor ary pas sword t o
each user. Most users will want to change their password. The changepass
command changes the passwor d for the current logged in user. The following
is an example of chang ing a pa s sword:
jsmith> changepass
Current Password: the password is case- se nsitive and will not appear as you type it
New Password : the password is case-sensitive and will not appear as you ty pe it
Confirm New Password : the password is case-sensitive and will not appear as you type it
User record updated.
Password change successful.
Configuring a DSL connection
The first step in configuring your Z-Edge 64 is connecting to the WAN by
setting up a DSL connection over the Z-Edge 64 WAN interface.
The dsl-config profile is automaticall y created by the system when the
Z-Edge 64 is turned on. Update the dsl-config profile to match your line-type
and unit-mode.
22 Z-Edge 64 Configuration Guide
Configuring a DSL connec ti on
The dsl-config profile supports the following parameters:
Parameter Description
line-type The DSL type supported on this
interface.
Values:
shdsl GlobespanVirata firmware for
G.SHDSL (not compatible with
shdsllatest firmware)
sdsl GlobespanVirata firmware for
SDSL (not compatible with sdsllatest
firmware).
shdsllatest Compatible with most
GlobespanVirata G.SHDSL firmware.
This value is required for automatic
rate adapti on on G.SHDSL.
sdsllatest Compatible with most
transparent mode ATM SDSL
impleme n tations. This v alue is
required for automa tic rate a dapti on on
SDSL.
Default: shdsllatest
unit-mode S p ec if i es w h et he r th e un i t is
configured as a CO or CPE device. If
you are connecting Z-Edge 64 units
back-t o -b a ck , set the unit-mode to co
(central office) on one Z-Edge 64, and
set the downstream Z-Edge 64 to cpe
(customer premises equipment).
Values:
co
cpe
Default: cpe
Below is an example showing the default settings for a dsl-config profile:
zSH> get dsl-config 1-1-1-0/hdsl2 hdsl2 type includes HDSL2, SDSL, and G.SHDSL
line-type: -> {shdsllatest} shdsl | sdsl | shdsllatest | sdsllatest
unit-mode: -> {cpe}
Depending on the line-type, configuration profiles are automatically created
for the DSL variations. To change the DSL variation, modify the line-type in
the dsl-config profile and then update the specific DSL confi guration profiles.

This chapter details how to configure system-wide settings of the Z-Edge 64.
It includes the following topics:
• System defaults, page 29
• Configuring a connection to the ZMS, page 30
System defaults
When the Z-Edge 64 is turned on, several profiles are automatically
configured. Here are some of the Z-Edge 64 defau lt configurations:
• The Z-Edge 64 is set up as a DHCP client in the ip-interface-record for
the WAN port of the system.
• The Ethernet (LAN) interfa ce is 10/100 Mbps autosensing,
autonegotiating.
• The DSL (WAN) interface is set to SDSL, customer premises equipment,
with a line speed of 1552kbps.
• The Virtual Path Indicator (VPI) and Virtual Channel Identifier (VCI)
values for the W AN interface: VPI/VCI = 0/35.
The Z-Edge 64 automatically creates ip-interface-record, atm-traf-descr
record and atm-vcl profiles for the WAN interface when the Z-Edge 64 is
turned on. Thes e thre e pr o file s enabl e ATM traffic over IP on the WA N por t.

The Z-Edge 64 uses DHCP to obtain configuration pa rameters, such as an IP
address, from a DHCP server. To act a s a DHCP c lient, the Z-Edge 64 must be
connected to the DHCP server over an active WAN connection. Set up the
WAN connection and the DHCP client configuration will occur as set up on
the DHCP server.
Configuring a connection to the ZMS
Note: Most of the parameters in the system profile should be left at
their default values. ZMS uses them to update status of the
configuration process.
The system profile is automatically created. The following parameter in the
system profile determines whether authentication failure traps are sent to
ZMS:
