Figure 1-3 Attaching the Ferrite Sleeve Around a Coaxial Cable
Figure 1-4 shows the typical 75-ohm RG-59 coaxial cable pair that you supply and should use with the
PA-MC-T3. Use only this type of coaxial cable pair for your PA-MC-T3 connections. Use one 75-ohm
coaxial cable for each PA-MC-T3 connection: RX and TX.
We strongly recommend that you fasten together your transmit and receive cables along their entire
length, as shown in Figure 1-4, which reduces the effects of EMI. You can use standard heat-activated
shrink tubing or cable ties for this purpose.

You can also order from Cisco Systems a 75-ohm coaxial cable pair with ferrite beads attached (Cisco
Product Number CAB-ATM-DS3/E3). (See Figure 1-5.) This 75-ohm coaxial cable pair is not available
from outside commercial cable vendors.
