ADTRAN SLC-5 U-BR1TE III Physical Requirements, Interface Requirements, Switch Option Settings

Page 4

NOTE

When the U-BR1TE III is optioned for B1 or B2, the SLC-2000 slot must be provisioned for D only. If the U-BR1TE III is optioned for 2B, then the SLC-2000 slot must be provisioned for B1+D.

Physical Requirements

The U-BR1TE III occupies one physical slot in the SLC-5 or SLC-2000 channel bank. The backplane pin assignments are illustrated in Figure 3.

Interface Requirements

The U-BR1TE III unit includes two interfaces. The loop-side interface is an ISDN U-interface which is used to deliver Basic Rate service. The carrier-side interface is a SLC-5 or SLC-2000 channel bank interface which is used to insert data into the 1.544 Mbps T1 stream. Only the polarity insensitive Tip and Ring leads are used in the cross-connection.

Switch Option Settings

See Figure 1 and Figure 4 for SW1 and SW2 location. The options for SW1 and SW2 are described in Table 2.
