Description
The RMM provides an industry standard interface to other network equipment. It can be
installed in any access module slot in either the Total Access 3000 (23-inch) or 3010 (19-inch)
shelves.
Features
The basic features of the Remote Management Module include the following:
• Provisioned by software only; no hardware switches
• Supports ESF framing format
• Operation over extended temperature range of –40°C to +65°C
• Meets NEBS Level 3 and GR-1089-CORE standards
• Ethernet bridging using PPP as the WAN encapsulation (per RFC 1661); No direct IP
addressing is required as access to the RMM is provided via Total Access 3000 common
equipment
• Timing can be recovered or generated locally
• DS1 interface is software-selectable (MUX-fed or DSX-1)
• Automatically switches between multiplexers upon MUX failure or removal (in MUX mode)
• Front panel access to Ethernet transmit and receive over a single RJ-45 CAT 5e cable
connected to the PCB
• Alarms generated for loss of WAN link (Layer 1 Framing), loss of WAN link (Layer 2 PPP), or
loss of Ethernet
• Supports both YModem and TFTP for field upgrades
• DS1/WAN interface responds to CSU loopback codes when lookback detection is enabled
• Six external alarm inputs for EMS or NMA notification through the six loop pairs normally
used for service delivery
• Six external alarms, sent via TL1 and SNMP, (two alarms in a Total Access 3000 High Cap
shelf; P/N 1181001L2) have programmable severity
• External alarms can be disabled remotely by a management entity, or locally by a
technician with ADMIN level privileges

INSTALLATION
Inspect the Remote Management Module. If damaged, file a claim with the carrier then contact
ADTRAN Customer Service. Refer to “Appendix A, Warranty” for further information. If
possible, keep the original shipping container for returning the Remote Management Module
for repair or for verification of shipping damage.
CAUTION
Electronic modules can be damaged by ESD. When handling mod-
ules, wear an antistatic discharge wrist strap to prevent damage to
electronic components. Place modules in antistatic packing mate-
rial when transporting or storing. When working on modules,
always place them on an approved antistatic mat that is electrically
grounded.
The RMM plugs directly into the Total Access 3000 (23-inch) shelf or the Total Access 3010
(19-inch) shelf. Both are rack mounted chassis, with 28 access module slots on the Total
Access 3000 and 22 access module slots on the Total Access 3010. Each access module
contains the interfaces and appropriate circuitry to interface with the local loop.

Instructions for Installing the Module
To install the Remote Management Module, perform the following steps:
1. If present, remove the Access Module Blank (P/N 1181953L1) from the appropriate access
module slot of the Total Access 3000 chassis.
2. Pull the ejector tab on the bottom of the RMM into the down (open) position.
3. Plug the CAT 5e Ethernet cable into the RJ-45 connector located on the circuit board.
NOTES
• Maximum CAT 5e cable length is 100 meters.
• To connect the RMM directly to the Ethernet port on the SCU, an
Ethernet cross-over cable is required.
4. Route the cable up through the notch at the top edge of the front panel. Secure it with a
small cable tie at the anchor slot, directly below the notch on the rear of the front panel.
5. Hold the RMM by the front panel while supporting the bottom edge of the module, and
align the module edge with the guide groove in the chassis.
6. Firmly push the RMM into the slot. Simultaneous pressure at the top and bottom of the
faceplate ensures a good seat of the module pins into the backplane connector.
If the chassis is operational, the module performs a self test at this point. When the self
test is complete, the LEDs indicate the correct status of the module. Refer to “Front Panel
LEDs” on page 6.
7. Push the ejector tab into the up (closed) position.

Remote Management Module Installation and Maintenance Practice
861181019L1-5C
OPERATION
The RMM can occupy any access module slot and terminates a DS1 signal in the Total Access
3000/3010 system.
Power Interface
The RMM receives power from the Total Access 3000/3010 system.
SCU User/Supervisory Interface
User access to the RMM is through the SCU via the system bus present on the Total Access
backplane. All menu items will be generated by the RMM. The SCU will initiate and control the
transfer of commands and data to and from the unit. All provisioning and data reporting will
take place over the communication bus.
Ethernet/LAN Interface
The Ethernet port automatically adjusts to accommodate 10 or 100 Mbps devices. Ethernet
pinout transmits on pins 1 and 2 and receives on pins 3 and 6.
DS1/WAN Interface
The DS1/WAN interface supports ESF framing, recovered or local timing, line coding, line
build out, and works at clock rates of 1.544 Mbps ±50 ppm. This interface responds to in-
band CSU loopback codes only when loopback detection is enabled. Refer to “In-Band
Loopbacks” on page 10 for more information.
The DS1/WAN port interfaces to a selected DS1 tributary within a DS3 or STS-1, depending
on the installed multiplexer, when Network Source is set to MUX.
Setting Network Source to DSX-1 connects the DS1/WAN port to to an external DSX-1
interface on Pair 7 and 8.
• Pair 7 = T1/R1 (input)
• Pair 8 = T/R (output)
Refer to “DS1 Network Source” on page 16.
PPP
The PPP link is a protocol that operates over the physical DS1/WAN interface and encapsu-
lates data traffic. The RMM PPP link consists of the LCP and BCP protocols and requires no
authentication. If the physical DS1/WAN interface goes into an alarm state, the PPP link also
goes into an alarm state.

Operation
61181019L1-5C 9
Alarms
All active alarms are recorded in the RMM alarm display and are also reported to the SCU. The
SCU maintains corresponding entries in its alarm log and also generates SNMP and TL1 trap
notifications.
Major level alarms are generated by the WAN/DS1 interface upon Loss of Signal (LOS), Loss of
Framing (LOF), receipt of Alarm Indication Signal (AIS), or receipt Remote Alarm Indication
(RAI). Upon detection of LOS, LOF, or AIS the WAN/DS1 interface transmits RAI toward the
MUX or DSX-1 interface (as selected).
A Major level alarm is generated by the LAN interface if the Ethernet link is down. A Major
level alarm is generated if the PPP link carried by the WAN/DS1 interface goes down for any
reason. An Alert level alarm is generated whenever the WAN/DS1 interface is placed into a
loopback mode, either manually or via in-band CSU loop-up codes. Table 5 summarizes
alarms generated by the RMM.
There are six external alarm inputs, consisting of two wires connectable through the Total
Access 3000/3010 loop I/O connectors (Pairs 1 – 6). The external alarm input is associated
with the “tip” connection which responds to the application or removal of –48 VDC. The “ring”
connection supplies a low current source of –48 VDC so the external alarm can be controlled
by shorting or opening the connection between the tip and ring through relay contacts. Each
external alarm can be programmed to activate upon the closing or opening of the contacts.
Each of the six (two on the Total Access 3000 High Cap) Loop I/O connectors provides a single
loop to each access module slot in the chassis. The “ring” side is associated with pins 1–28 on
the connector, and the “tip” side is associated with pins 33–60. For example, ring and tip
connections for slot 5 on a particular connector would be pins 5 and 37. External alarm
inputs 1–6 are associated with pairs 1–6, respectively.

Loopbacks
The following loopback options are supported by the RMM module.
• Manual Loopbacks
• In-Band Loopbacks
• Loopback Timeouts
Manual Loopbacks
CAUTION
Do not invoke a DS1 loopback if the RMM is being configured
remotely and the management link is provided by the RMM.
The RMM can be set into loopback mode manually through the SCU interface. Table 6 lists
the loopbacks and their descriptions.
In-Band Loopbacks
When loopback detection is enabled, the DS1/WAN interface responds to unframed, in-band
CSU line loop codes sent from the network direction. The loop-up code is 1-in-5
(binary 10000) and the loop-down code is 1-in-3 (binary 100). The codes must be sent for at
least five seconds for the unit to respond.
Loopback Timeout
The RMM has a default loopback timeout of 120 minutes, but can be set to 90 minutes, 60
minutes, 30 minutes, or disabled through the SCU interface.
Table 6. Loopback Options
Loopback Options Description
DS1 Line loopback Loops the DS1 port data toward the MUX/DSX-1 before it reaches the DS1
framer circuit
DS1 Payload loopback Loops the DS1 port data toward the MUX/DSX-1 after it reaches the DS1
framer circuit
None Drops all active loopbacks and enables normal operation

Menu Structure
61181019L1-5C 11
MENU STRUCTURE
The SCU provides a menu system for the Total Access 3000 shelf. All system-related menus
are controlled by the SCU. Each access module has its own user menu structure supported by
the module.
The menu structure for the RMM is a layered menu tree. Each menu level consists of
submenus and/or menu items. Some menu items are restricted to certain user accounts. The
ADMIN account allows changes to all provisionable settings as well as network configuration
settings that are not accessible to READWRITE and READONLY accounts. Figure 2 on page
12 illustrates the menu structure of the RMM.
Submenus are elements which move down to the next menu level. Menu items are elements
used to make changes to the current SCU settings. There are two different types of menu
items: read-only and read-write.
A read-only menu item displays information that can not be changed, such as the status of
the RMM. A read-write menu item displays information that can be changed, such as DS1
framing.
NOTE
Menus can be accessed during a TL1 session by typing menus;.
