OK, let me start by describing the equipment in my house installed by
CenturyLink (probably more detail than is necessary):

The 'ADTRAN': There is a white plastic device about the size of a DVD
case, except about twice as thick. The fiber from the street plugs into
it, as does its power cord from the wall wart, and one ethernet cable.
If I recall correctly, the installer guy said its purpose was to
translate the signal from the fiber to ethernet. It has a label that
says:

ADTRAN
Model NameI:NDOOR SFU GEN3
Model No.: TA324
Power Rating: 12V 1.5A
P/N 1287735G3 Rev B
FSAN : ADTNAA 100ABB
MAC 00:19:92:B2:31:B5
Manuf. date 2016-03-03

The other end of the ethernet cable plugged into the ADTRAN is plugged
into the 'modem.' The 'modem' is twice the size of the Netgear modem
that I used with Comcast. On the front it has the following
blinkenlights (all lit up or blinking except those with *):

Power
DSL 1 *
DSL 2 *
Internet
WAN/LAN
1
2 *
Ethernet
3 *
4 *
HPNA *
USB
WiFi 2.4 GHz
WiFi 5 GHz
VOIP-1 *
VOIP-2 *
WPS

It has a label which says:
SSID - 2.4 GHz CenturyLink1080
SSID - 5 GHz CenturyLink10805G
Security type: WPA2-AES
Key Passphrase *******
WPS Pin ******
GUI Address 192.168.0.1
Admin Username: admin
Admin Password: *******

The installer left the box that the 'modem' came in because I told him
that I would be returning it as soon as I get my own. There is a label
on the box:

CenturyLink SN: CP1640ABA5R1080
CPRO: C2100TV4
Gw: BAC2100TV4
MAC: 10:13:31:07:02:7E

Inside the box are a couple of papers for the license agreement, safety
instructions and regulatory notices, all from an outfit called
'technicolor' www.technicolor.com

In the back of the 'modem', in addition to a power cord from its wall
wart, are ethernet jacks; one has the cable from the ADTRAN, and the
other has a cable to the WAN jack on my Netgear router. The latter
cable used to go to the back of the Comcast modem.

>From what Russell et al. have said here, and from what I can see
myself, it appears that the 'modem' is not a modem as we normally think
of a modem, rather, it appears to function more as a router. I haven't
used its wifi because the Netgear has wifi (only used for my phone and
laptop, although the laptop is normally wired). Russell says I need
pppoe and VLAN and that these might be doable with the Netgear. I
logged into the Netgear router and found a VLAN / Bridge Settings page,
which had a big checkbox for 'Enable VLAn / Bridge Setup.' It was not
checked and I left it unchecked for now. I didn't find anything that
said pppoe, but probably I just don't know what to look for.

Any thoughts?
