DNX-1u Access Gateway

Platform for TDM-Centric Radio Access Networks

Octal 10/100 Ethernet Switch/Router

ANSI T1.617; IEEE 802.3; 8 x RJ-45; IEEE 802.3x
8 auto-sensing 10/100 Ethernet interfaces with Layer 2 switching and channelized/unchannelized routing

Dual High Speed Data

EIA-232; EIA-449/422; EIA-530; ITU X.21; ITU V.35; 2 x micro DB26
2 soft-selectable ports can be directed to the cross-connect or function as WAN ports to the routing engine; can operate at all Nx56/64 Kbps data rates with a maximum speed of 2.048 Mbps

Terminal Server Ports (6)

EIA-232 DTE; ITU V.24 DTE; 6 x RJ-45
User programmable with regard to speed, character length, parity, and stop bit; maximum baud rate of any port is 38.4 Kbps; support one control signal per direction

Voltage Measurement

Input voltage range is 0 to ±60 volts; resolution is ~100 mv
Software thresholds can be set to establish limits on measured voltages; variation from these limits can trigger an SNMP trap; can be soft configured as single ended inputs or as differential pairs referenced to chassis ground

Transcoder

CCITT G.726 at 32 Kbps
32 channels of full duplex PCM to ADPCM transcoding at 2:1 compression, globally set; the transcoder is compatible with both µ-law and A-law encoding for use with either T1 or E1 links

Contact Inputs

Form C 2 x 9 position Phoenix connectors
Supports 16 input alarm ports (soft configurable port definition, soft defined polarity); an active received alarm input can trigger an SNMP trap; TTL compatible signal, or sense a contact closure; over-voltage and polarity protected up to ±60 volts

Contact Outputs

Form C 2 x 9 position Phoenix connectors
Provides 6 output alarm ports with no/nc contacts; contact closures are soft defined

Quad T1/E1 Module (System capacity 2 modules or 8 T1/E1 interfaces)

ANSI T1.403; TR 62411; TR 54016; ITU G.703; ITU G.704; ITU G.826
(8 x RJ-48C) Global software selection for T1/E1 is required; D4, ESF or G.70x framing and AMI, B8ZS or HDB3 line coding are supported; the module can operate in short or long haul formats and includes integral BERT and loopback diagnostics; integral APS functionality for 1:1 and 1+1 applications in revertive and non-revertive modes; all features soft-selectable

Cross-Connect Capacity

Non-blocking TDM switch fabric with a capacity of 1024 DS0s (64 Mbps); DS0 and DS1 switch resolution

Routing Features

RIP, RIP2, OSPF, Frame Relay, NAT/PAT, DHCP, Packet Filtering, MLPPP

Management Features

Telnet, Reverse Telnet, SNMP, TACACS+, craft interface (9600 to 38400 bps, async, 8N1, via an RJ-45) Router CLI, ENvision EMS, ENvision Plus NMS

Power

±21 to ±60 VDC; 1.4 Amps maximum
Each module has a separate input feed located on the rear of the unit; modules are field replaceable

Mechanical

420 mm W x 305 mm D x 45 mm H (16.5" x 12" x 1.75")
4.09 kilograms (9 pounds) fully configured

Environment

NEBS-compliant design
-20°C (-4°F) to +65°C (149°F) Temperature
0% to 95% Humidity (Non-Condensing)

Compliance

CE, IC, FCC, UL/CUL, NOM, AS/NZ, ACA, TEC, CNACL, RoHS
