Control Plane Connections Between the TX Matrix Router and T640 Router
The control plane connections between the T640 routers and the TX Matrix router are provided by UTP Category 5 Ethernet cables between the RJ-45 ports on the TX-CIPs in the TX Matrix router and the T-CBs in the T640 routers. The maximum length supported is 100 m. The UTP Category 5 cables do not have to be the same length. The cable wiring is straight-through (not crossover).
Table 1 shows these connections. Each column represents a TX-CIP (TX-CIP-0 and TX-CIP-1), and each cell within a column represents a port on that TX-CIP. Each cell specifies the TX-CIP port (LCC0 through LCC3) and its connection to the port labeled CIP on a T-CB in one of the T640 routers. For example, port LCC0 on TX-CIP-0 is connected to T-CB-0 in chassis LCC0, port LCC1 on TX-CIP-0 is connected to T-CB-0 in chassis LCC1, and so on.
 | Note: The RJ-45 port labeled AUX on a T-CB is reserved for future use. |
The cable connections provided in Table 1 apply to routing matrix configurations using from one through four T640 routers. For example, if you have a single T640 router in your configuration, the connections from each TX-CIP to chassis LCC0 are presented in the first row of the table. If you have two T640 routers in your configuration, the connections from each TX-CIP to chassis LCC0 and LCC1 are presented in the first two rows of the table, and so on.
| Note: The RJ-45 ports labeled LCC4 through LCC7 on a TX-CIP are reserved for future use. |

TX-CIP-0 Port and Destination | TX-CIP-1 Port and Destination |
|---|---|
LCC0—T-CB-0 in LCC0 | LCC0—T-CB-1 in LCC0 |
LCC1—T-CB-0 in LCC1 | LCC1—T-CB-1 in LCC1 |
LCC2—T-CB-0 in LCC2 | LCC2—T-CB-1 in LCC2 |
LCC3—T-CB-0 in LCC3 | LCC3—T-CB-1 in LCC3 |
Figure 1 shows the control and switching planes connections between the TX Matrix router and a T640 router. The control plane connections are in the center.
