• 4-port asynchronous/synchronous serial network module—(Cisco product number
NM-4A/S). (See Figure 6-11.)
• 8-port asynchronous/synchronous serial network module—(Cisco product number
NM-8A/S). (See Figure 6-12.)
With the appropriate serial transition cable, the ports on these modules can provide an
EIA/TIA-232, EIA/TIA-449, V.35, X.21, DTE/DCE, EIA-530 DTE, or NRZ/NRZI serial
interface.
