NM-1FE-TX Features at a Glance

• RJ-45 connector to attach to Category 5 unshielded twisted-pair

(UTP; for example, 10 or 100BaseTX)

• Support for Inter-Switch Link (ISL) over Fast Ethernet

to ensure compatibility with the Catalyst

5000, Catalyst 5500,

and Catalyst 3000 switches

• Will conform with the IEEE 802.1Q Fast Ethernet speciﬁcation,

ensuring multivendor interoperability when the standard is

ﬁnalized

• 10 or 100BaseTX operation, autosense

• Full- and half-duplex operation

• An LED indicates when the network module is “ENabled” for

operation

• Four additional LEDs indicate collision, link, 100-Mbps mode,

and full duplex operation status

NM-COMPR Features at a Glance

• Occupies a single slot in a Cisco 3620 or 3640

• Coprocessor design with no external LAN or WAN ports

• Supports all serial, Integrated Services Digital Network

(ISDN), and channelized WAN network modules and

WAN interface cards

• 2E1 full duplex (2 x 2.048 Mbps Full Duplex) of compressed

input/output

• Up to 128 virtual circuits with dedicated memory for

compression histories

• Industry-standard STAC (QIC-122)

• Point-to-Point Protocol (PPP) (at FCS) and Frame Relay

encapsulations (late 1997)

• Link-layer compression

NM-4E Features at a Glance

• Attachment user interface (AUI) and an RJ-45 connection

onboard for the ﬁrst Ethernet port and RJ-45 only connections

on the remaining three ports

• Half-duplex operation

• An LED indicates when the network module is “ENabled” for

operation

• Separate LEDs for each port indicate link and active status for

that port

NM-4T Features at a Glance

• Each port supports a full-duplex operation at T1 and E1 speeds

• All ports use identical 60-pin, D-shell receptacle that supports

all interface types (that is, RS-232, RS-449, RS-530, V.35,

X.21)

• Interface type (that is, RS-232, RS-449, RS-530, V.35, X.21)

and port mode data terminal equipment (DTE) or data

communications equipment (DCE) operation determined by

separately purchased cable

• An LED indicates when the network module is “ENabled” for

operation

• Separate LEDs for each port indicate transmit data, transmit

clock, receive data, and receive clock signals
