AT-CM70S Converteon Line Card Installation Guide
Overview
The AT-CM70S line card is a 10/100 Mbps Ethernet copper-to-fiber media converter line
card that provides Time Division Multiplexing (TDM) (T1/E1) transport in addition to
regular Ethernet traffic and OAM link management capability. This line card offers support
for 1.544 Mbps (T1) and 2.048 Mbps (E1) services with complete synchronization for toll-
quality transport of voice, video, and data. It also accommodates traditional testing
equipment currently used on SONET/SDH equipment for testing T1/E1 services. You can
install the AT-CM70S line card in any Converteon Series chassis except the AT-CV1000.
The AT-CM70S line card is hot swappable into and out of a Converteon chassis. The line
card requires two adjacent line card slots.

AT-CM70S Line Card Components
An AT-CM70S line card has the components shown below.
Port Descriptions
SFP Port
The SFP port supports an SFP transceiver with a fixed operating speed of 100 Mbps. The
port multiplexes the T1/E1 and twisted pair ports into a single fiber interface for a
distance of up to 40 km. Another AT-CM70S line card must be installed in the remote
chassis to de-multiplex the signals.
Console Port
The console port allows you to configure the AT-CM70S line card when no AT-CV5M0x
management card is installed.
Note
By default, the console port is active. However, if you configure the AT-CM70S line
card using the management software, ensure that the operating mode is “Line Card
DIP Switch” mode to keep the console port active. You cannot configure this setting
using the DIP switches on the line card.
The default settings for the RS-232 console port are:
‰ Baud rate: 115200 bps (range 2400 to 115200 bps)
‰ Data bits: 8
‰ Parity: None
‰ Stop bits: 1
‰ Flow control: None
A console port cable is provided.
Twisted Pair Port
The 10/100Base-TX compliant twisted pair port has an RJ-45 connector and a maximum
operating distance of 100 meters (328 feet). Category 5 (5E), 100 Ohm shielded or
unshielded twisted pair cabling is required. The pinouts for this port are shown in
“Twisted Pair Port Pinouts.”
T1/E1 Ports
Each T1 port supports a maximum rate of 1.544 Mbps and a maximum line length of
6000 ft. over 100 Ohm balanced cable. Each E1 port supports a maximum rate of 2.048
Mbps and a maximum line length of 2.5 km over 120 Ohm balanced twisted pair cable.
LEDs
The AT-CM70S line card has three status LEDs, one LED for the SFP port, three LEDs for
the twisted pair port, and four LEDs for each T1/E1 port as described in “LED Descriptions.”
DIP Switches
One set of two DIP switches allow you to set the operating mode of the line card, as
described in “DIP Switch Settings.”
Recessed CPU Reset Button
The recessed CPU RESET button allows you to manually reset the AT-CM70S line card
when the chassis does not contain an AT-CV5M0x management card or when an
AT-CV5M0x management card is installed but you cannot reset the card through the
management software.
Installing an AT-CM70S Line Card
Note
Before you install an AT-CM70S line card, refer to the appropriate Converteon
chassis installation guide for electrical safety and emissions information.
Note
You can install this Converteon line card in any two adjacent Converteon chassis
line card slots.
To install an AT-CM70S line card, perform the following procedure:
1.
Remove the AT-CM70S line card from its shipping package and store the package in
a safe place. You must use the original package if you need to return the unit to
Allied Telesis.
2. Configure the line card’s DIP switches as required. Refer to “DIP Settings” for more
information.
3. Select two adjacent line cards slot in the chassis where you want to install the
AT-CM70S line card and remove the blank slot covers if they are installed.
4. Align the back edge of the line card with the top and bottom alignment guides located
inside the slots.
5. Slide the line card into the slots until the front of the card is flush with the front of the
chassis.
Note
Avoid touching the line card components.
6. Secure the AT-CM70S line card to the chassis by using a Phillips screwdriver to
tighten the captive screw on the faceplate.
Note
Always tighten the captive screw to secure the line card to the chassis.
LED Descriptions
Status LEDs
The line card has three status LEDs as described in the following table. For more
information about OAM, refer to the relevant management software user’s guide.
SFP Port LED
The SFP port has one LED, as described in the following table.

Warning: Remove all metal jewelry, such as rings and watches, before installing
or removing a line card from a powered-on chassis.
Caution: Be sure to observe all standard electrostatic (ESD) precautions, such
as wearing an antistatic wrist strap, to avoid damaging the device. A line card can
be damaged by static electricity.
Caution: Before installing this line card in an AT-CV120x chassis, ensure that the
chassis is grounded as described in the AT-CV120x Chassis Installation Guide.
