E&M/TO
STATUS
AP
DESCRIPTION
The E&M/TO is a channel unit that provides an interface between a Total Access
®
750/850/1500 channel bank PCM interface and a VF transmission facility with E&M
DC signaling supervision. The E&M/TO features:
■
E&M or TO Mode
■
Dial pulse distortion correction option
■
Digital loopback to the network,
■
Compatible with types I, II, III, or V E&M signaling interfaces
■
2-wire or 4-wire mode
Note: Use in a Total Access 850 requires a BCU.
TURNUP STEPS
Unpack the Total Access 750/850/1500 E&M/TO card and inspect for damage. If
damage is apparent, refer to your carrier or supplier for replacement.
Verify SW2, SW3, and SW4 are provisioned properly for your application. Refer to
the table in this job aid for default provisioning and other provisioning options.
Insert E&M/TO card into a Total Access 1500 chassis slot 1-24, or Total Access 750
Chassis slots 1-6. To insert, hold the card by the front panel while supporting the
bottom edge of the card. Align the card edge with the guide groove in the Total
Access 750/850/1500 chassis. Insert into chassis until the edge card connector
seats firmly into the chassis backplane. Lock the unit in place by pushing in on
the locking lever. The unit will automatically map DS0s in the T1 determined by
the LIU operational configuration. Automatic assignment can be overridden by
manually changing the T1 mapping in the LIU menuing system.
Verify LED sequencing. LEDs will stop sequencing once unit is initialized.

Provisioning – The Total Access 750/850/1500 supports two types of provisioning modes, local and
remote. Local provisioning results in the unit operating as defined by the onboard switches.
Remote provisioning, if chosen, results in the unit operating as defined by the system controller
menu settings (onboard switches are ignored). The operational mode is indicated by the REM LED
and can be changed by activating the Alternate Provisioning (AP) front panel switch.
Connect VT100 compatible terminal to BCU/SCU front panel ADMIN port.
6a. Connect DB-9 cable
6b. Run terminal emulation program
6c. If using Windows HyperTerminal, open by selecting Programs/Accessories/Hyperterminal
6d. Login and navigate through the ADMIN port menu structure
Note: To ensure proper display background, select VT100 Terminal Emulation under settings.
Navigate through menus to perform desired function.
Note: To traverse through the menus, select the desired entry and press Enter. To work backward in the
menu, press ESC (escape key).
