I work for an ISP who has seen a lot of Alcatel modems. There were some
firmware versions where the modem would crash. If its a speed touch, see
about updating the firmware if possible.

Actually, just ifconfig rl1 media 10baseT/UTP will put it into half =
duplex
mode. The assumption being that without specifying media-opt, you get
half-duplex on 10baseT/UTP
e.g.
cage# ifconfig rl0
rl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
inet6 fe80::250:fcff:fe05:2624%rl0 prefixlen 64 scopeid 0x2=20
ether 00:50:fc:05:26:24=20
media: autoselect (none) status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP 100baseTX <hw-loopback>
cage# ifconfig rl0 media 10baseT/UTP
cage# ifconfig rl0
rl0: flags=3D8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
inet6 fe80::250:fcff:fe05:2624%rl0 prefixlen 64 scopeid 0x2=20
