4.2 Environment

It is recommended to take some security measures for the site to prevent
tampering with the equipment (for example a locked cabinet).

The ambient temperature around the equipment must be within 0 – 45 ºC.
The relative humidity must be within 5% - 95%, non condensing.

Configuring the CPE Modem

The CPE Modem must be configured to map the VLANs used by the IP
DSLAM to PVCs towards the Central Office (see Figure 4 on page 8). It
must be configured to use the PVCs (VPI, VCI) used by the Central Office
DSLAM, and the Management and Data VLAN IDs used by the IP DSLAM.

Note: The Management VLAN ID does not necessarily have to be the

same VLAN ID as the ID used in the EDA network (although it is
recommended to use it to avoid confusion).
