TXP-F13 SIB Description

TXP-F13 SIBs are hot-removable and hot-insertable (see Figure 1).

Each TXP-F13 SIB consists of the following components:

• Switch Fabric ASICs.
• High-speed electrical links through the midplane to the TXP-F2S SIBs on the same switching plane.

These components are located on the TXP-F13 faceplate:

• Eight high-speed fiber-optic links connect to two T1600 routers in the routing matrix. The left four ports are labeled EVEN and provide connections to one even-numbered LCC—LCC0 or LCC2.The right four ports are labeled ODD and provide connections to one odd-numbered LCC—LCC1 or LCC3. The four ports on each side are labeled CBL A, CBL B, CBL C and CBL D.
• Three ONLINE/OFFLINE buttons are located in the middle of the TXP-F13 SIB.
  • The ONLINE/OFFLINE button labled LCC EVEN brings the corresponding interface and TXP-T1600 SIB on the even T1600 router online and offline.
  • The ONLINE/OFFLINE button labled LCC ODD brings the corresponding interface and TXP-T1600 SIB on the odd T1600 router online and offline.
  • The ONLINE/OFFLINE button in the center labeled SIB brings the TXP-F13 SIB online and offline.
• Three status LEDs, labeled ACTIVE, OK and FAIL, located below the ONLINE/OFFLINE buttons.
• Two port LEDs, labeled LINK and RxPWR, located to the right of each fiber-optic array port.

Three LEDs, labeled OK , FAIL, and ACTIVE are located on the craft interface; they show the status of the link to the T1600 router.

TXP-F13 SIB Slots

Sixteen horizontal TXP-F13 SIB slots numbered 0 through 15 (top to bottom) are located in the rear of the TX Matrix Plus router. A TXP-4 configuration contains ten TXP-F13 SIBs, two for each data switching plane. The remaining slots are unused.
