TN464HP and TN2464CP Option Settings

The TN464HP DS1/E1 Interface - T1/E1 circuit pack interfaces between a 24- or 32-channel Central Office/ISDN or tie trunk and the TDM bus.

Note:

The P designation means the circuit pack’s firmware is programmable. Refer to Upgrade Firmware on Programmable Circuit Packs on page 231 for more information.

Set the switches on the circuit pack to select bit rate and impedance match. See Table 34 and Figure 70: TN464HP and TN2464CP Option Settings on page 161. If the top switch setting is set to 32 channel, then set the lower switch setting to either 120 ohms or 75 ohms.

Table 34: Option Switch Settings on TN464HP and TN464CP

120 ohms	Twisted pair
