Cabling and Configuring the
CES Port Adapter Modules
This chapter describes cabling and configuration procedures for the LightStream 1010
asynchronous transfer mode (ATM) switch circuit emulation service (CES) T1 and E1 port
adapter modules (PAMs). When your switch leaves the factory, it is configured as specified
in your order and is ready for installation and startup. As your communication requirements
change, you might want to upgrade your system, add components, or change the initial
configuration.
The following CES T1 and E1 PAMs are described in this chapter:
•
•
•
CES T1 Twisted-pair Port Adapter Module
CES E1 Twisted-pair Port Adapter Module
CES E1 BNC Port Adapter Module
Software and upgrades require specific document part numbers and other frequently
updated information; therefore, only basic software configuration guidelines are included
in this publication. Detailed, up-to-date instructions are included in the LightStream 1010
ATM Switch Software Configuration Guide and command line interface (CLI) command
descriptions are provided in the LightStream 1010 ATM Switch Command Reference.

Overview of the CES Port Adapter Modules
The circuit emulation service (CES) T1 and E1 Port Adapter Modules (see Figure 8-1) are
ideal for links that require constant bit rate (CBR) services such as interconnecting PBXs,
time-division multiplexers, and video conference equipment over campus, public, or
private networks. The four ports on the PAM can be configured as redundant links using the
switch's routing protocols. The T1 PAMs support UTP connectors and the E1 PAMs
support either twisted-pair, STP, or 75-ohm BNC connectors. Status and carrier detect
LEDs on each port give quick, visual indications of port status and operation. For detailed
network management support, comprehensive statistics gathering and alarm monitoring
capabilities are provided.

Each of the ports on the PAM can be configured to support the following clocking options:
•
•
•
self-timing based on a Stratum 4 level clock
loop timing from the received data stream—ideal for public network connections
timing synchronized to a selected master clock port, required in order to distribute a
single clock across a network
The plug-and-play mechanisms of the LightStream 1010 allows the switch to come up
automatically. All configuration information for port adapter modules can be saved
between hot swaps and switch reboots, while interface types are automatically discovered
by the switch. This eliminates mandatory manual configuration.
The LightStream 1010 supports any combination of port adapter modules. Customers can
configure their switches with only the number and type of interfaces required, with up to
32 CES T1 or CES E1 interface ports.

CES Connection Equipment
For CES traffic over twisted-pair, use the RJ-48C connect to connect the CES T1 PAM or
CES E1 PAM to the external CES network. See the section “Preparing Network
Connections” in the chapter “Preparing for Installation” for a description of an RJ-48C
connector and twisted-pair and shielded twisted-pair cable.
For coaxial traffic, use the BNC connector to connect the CES E1 PAM with the external
CES network. See the section “Preparing Network Connections” in the chapter “Preparing
for Installation” for a description of a BNC connector and coaxial cable.
CES T1 and E1 PAM Network Connections and LEDs
The CES T1 and CES E1 PAMs provide an interface to CES switching fabrics for
transmitting and receiving data at up to 1.544 Mbps (T1) and 2.048Mbps (E1)
bidirectionally. The PAM LEDs provide status information for the port adapter module’s
individual interface connections.
Caution
T1 and E1 port must be connected to an NT1 device.

Note During alarm integration, the indicated LEDs will flash the “upcoming” or “next”

machine is notified of loss of signal (LOS), it will cause S1 and S2 to flash red, since a
continued LOS will put the port in the red alarm state.

Configuring the Interfaces
Configuring the Interfaces
When the switch is powered on initially without any previous configuration data, the ATM
interfaces are automatically configured on the physical ports. ILMI and the physical card
type are used to automatically derive the ATM interface type, UNI version, maximum
virtual path identifier (VPI) and virtual channel identifier (VCI) bits, ATM interface side,
and ATM UNI type.
Default ATM Interface Configuration Without Autoconfiguration
If ILMI has been disabled or if the connecting end node does not support ILMI, the
following defaults are assigned to all CES T1 and CES E1 interfaces:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
ATM interface type = UNI
UNI version = 3.0
Maximum VPI bits = 8
Maximum VCI bits = 14
ATM interface side = network
ATM UNI type = private
Loopback = no loop
Signaling mode = no signaling
Clock-source = network derived
Data format = clear channel
Timing = synchronous
Line build out = 0 to 110 feet
Cell delay variation = 2,000 microseconds
Channel associated signaling = false
Partial fill = 47
Cabling and Configuring the CES Port Adapter Modules 8-11
Configuring the Interfaces
The following PAM types have specific defaults assigned:
CES T1 PAM:
•
•
•
Framing = ESF
Line coding = B8ZS
Line state = no alarm
CES E1 PAM:
•
•
•
•
•
Line type = E1
Line coding = HDB3
International bits = 0x3
National bits = 0x1f
Multi-frame spare bits = 0xb
The following defaults apply for all versions of the CES modules, unless you change them
manually by means of specific CLI commands issued during module configuration:
•
CES-IWF AAL1 service unstructured—This default setting automatically
establishes unstructured (clear channel) CES services for a CES module.
•
CES-IWF AAL1 clock source synchronous—This default setting automatically
establishes synchronous clocking for all CES-IWF operations.
Note You can accept the default ATM interface configuration or overwrite the default
interface configuration using the CLI commands. These commands are described in the
LightStream 1010 ATM Switch Software Configuration Guide, which provides detailed
ATM interface configuration tasks.
This concludes the explanation of the CES T1 and CES E1 port adapter module cabling and
configuration.
