WebEML User Manual

43.10 PDH to Ring:

Caution: In the protected Core configuration, entering E1/DS1 cross-connections while the
spare Core is Active may affect existing E1/DS1 cross-connections. To prevent this from
occurring, ONLY provision E1/DS1 cross-connections while the main Core card is Active.
Caution: When parallel radio paths exist between two MSS shelves, port segregation
should be provisioned between the parallel radio paths at both ends to prevent a loss of
traffic.

43.10.1 Prerequisites

Each E1/DS1/DS3 port and Ring port must be enabled on the respective E1/DS1/
DS3 card and Ethernet Ring Protection Configuration provisioning screens.
The Service Profile on each E1/DS1/DS3 card Settings screen must be set to
TDM2TDM for each E1/DS1/DS3 cross connect when both termination points of the
E1/DS1/DS3 circuit are terminated on 9500 MPR equipment.
The Service Profile on each E1/DS1/DS3 card Settings screen must be set to
TDM2ETH for each E1/DS1/DS3 cross connect when one of the termination points
of the E1/DS1/DS3 circuit are terminated on non-9500 MPR equipment, and the
other equipment is MEF-8 compliant.
Each E1/DS1/DS3 line to be cross connected must have a unique Flow ID number
assigned to it on the respective E1/DS1/DS3 card Settings screen. Each E1/DS1/
DS3 Flow ID must be added and applied to the ERP Instance on the Ethernet Ring
Protection Configuration provisioning screen.
Verify appropriate port segregation is provisioned to prevent message flooding. Port
segregation should be provisioned between parallel radio paths at both ends when
they exist on the NE. Port segregation should also be provisioned between the radio
port and other Ethernet and/or radio ports where connectivity is not desirable.
