20 Intel NetStructure® MPRTM0020 Technical Product Specification – April 2006
Module Components
Note: The SAS_RX3 and SAS_TX3 interfaces are not physically connected to the SAS controller on
MPCBL0020. The physical routing for these signals exists on the MPRTM0020 but is not
supported on the SBC. See Figure14 “Physical Breakdown of SAS Ports Distribution” on page 27
for further details.
4.3.5 T1/E1 Connector Interface
Six T1/E1 RJ-48 connectors are present on the RTM. These connectors are designed primarily for
intra-building applications. Figure 11 shows the physical outline of the E1/T1 connectors and
Table 6 shows pinout information for each connector.
