For head offices, larger branches and aggregation points.Is this the right router series for you?
Plain-language guide — based only on what these routers actually do.
Internet gateway for an office or siteOne box for the edge: static, dynamic and PAT NAT with multiple NAT exits and NAT logs, a stateful firewall, ACLs, anti-ARP and anti-DoS/DDoS, DHCP server and H-QoS to keep voice and video ahead of downloads. Size by users: 300–500, 500–800 or 800–1,500.
Head office and branch VPNBranches, chain stores, schools and bank outlets join head office over IPSec, DMVPN or GETVPN on ordinary internet lines, or over L2TP, GRE and MPLS VPN on carrier networks; VXLAN over IPSec/GRE and EVPN are listed for overlay designs. A 3G/LTE link with smart dial control (SDC) keeps the site online when the wired line fails.
ISP enterprise CPE and legacy linesFor operators and integrators handing over leased lines: E1/CE1, V.35/V.24 serial and, on the 2800-4/3800-8, OC-3/STM-1 and OC-12/STM-4 POS/CPOS cards, with PPP, PPPoE, HDLC and FR, MPLS L2/L3 VPN and PWE3, BGP and IS-IS, and VRRP and BFD for redundancy.
Not the right pick if you need…
- Aggregation or core routing for many branches or a regional backbone — the ZTE Wantong ISG 5800/6800 aggregation and core routers sit above this series
- A small DIN-rail or cabinet router with a SIM for outdoor poles, solar CCTV or machines — the ZTE Wantong ISG IR industrial routers (IR111/112/121/122/520/530)
- Dedicated next-generation firewall inspection or PoE power for cameras — the ZTE Wantong ISG F-series firewalls, and PoE access switches such as the S5160-HE series

Who uses it, where it goes and how to plan the access router
Written for the ZTE Wantong ISG 18/28/38 series from its own specifications: 3 models for 300–500, 500–800 and 800–1,500 users, GE Combo and RJ45 ports, 2 to 10 card slots, 3G/LTE, E1, serial, POS and 10GE options, single or 1+1 power.
Who it is for
- SMEs and branch offices — One router as the office gateway: NAT and stateful firewall for internet access, DHCP server for the LAN, IPSec or DMVPN back to head office, and H-QoS so calls and video meetings keep priority.
- Chain stores, schools and bank outlets — Many similar sites on one template: USB-drive or SMS deployment to bring each router up, DMVPN or GETVPN to the centre, 3G/LTE with SDC as backup, and NMS batch upgrades from head office.
- ISPs delivering enterprise lines — A CPE that terminates fibre, E1, serial or POS lines and carries MPLS L2/L3 VPN, PWE3, BGP and IS-IS, with Eth OAM, MPLS OAM, SQA and NetFlow for monitoring the service.
- CCTV and security integrators — The router at a camera site for remote viewing: static NAT or PAT to publish the NVR, or better an IPSec VPN to the monitoring centre, with QoS for video and an LTE link as backup where fibre is unreliable.
Where and how to install
- Rack or shelf — The 2800-4 and 3800-8 are 442 mm wide (19-inch) and 88.1 mm and 132.0 mm high, 200 mm deep, so they fit a standard rack or a wall cabinet. The 1800-2S is 380 mm wide and 43.6 mm high — place it on a shelf or ask us about mounting parts for your cabinet.
- Power feeds — The 1800-2S runs on AC 100–240 V or DC -48 V with one supply, so put it on a UPS. On the 2800-4 and 3800-8 fit both supplies and feed them from two sources — for example mains AC and a -48 V DC or 240/336 V HVDC plant, since mixed AC and DC is allowed.
- Temperature and airflow — Rated -5°C to +45°C and 5%–95% humidity, non-condensing. Fans adjust their speed automatically; keep the air paths open and avoid closed cabinets in direct sun. For hot outdoor cabinets an industrial router is the better fit.
- WAN lines and cards — Fibre internet goes into a GE Combo port with an SFP module; copper lines use the RJ45 side. E1, V.35/V.24 serial, POS/CPOS and 3G/LTE need the matching interface card in a free slot, and POS/CPOS and 10GE cards are listed only for the 2800-4 and 3800-8.
- Antennas and SIM — With the 1800-2S(G) or a 3G/LTE card, check signal at the exact install point before mounting; place the router or the antenna lead where the signal is best, away from metal cabinet walls.
ISG access router planning: which of the 3 models
All three run the same software features (routing, VPN, NAT, QoS, firewall, IPv6, MPLS); they differ in users supported, fixed ports, card slots, interface cards and power. The manufacturer publishes no throughput or session figures, so size by recommended users and interfaces. Total slots is the sum of SPIU, PIU and DPIU slots.

| Typical role | branch, store, outlet gateway | head office / large branch | head office / aggregation access |
- Pick the 1800-2S(G) for a branch or camera site where 3G/LTE is the main or backup link and one power supply is acceptable; the 1800-2S(W) adds built-in Wi-Fi for a small office.
- Pick the 2800-4 when the site needs redundant power, POS/CPOS or 10GE cards, or more than two interface cards, for 500–800 users.
- Pick the 3800-8 for 800–1,500 users or a head office that terminates many lines: eight GE Combo ports, a listed 2×10GE version and 10 slots in total.
— = not listed / not applicable. Values are from the page's specification tables; total slots is our arithmetic (SPIU + PIU + DPIU). Recommended users is the manufacturer's 带机量 (devices behind the router). No throughput, NAT session or VPN tunnel figures are published for this series.

Engineer's note: The router is ordered as a base unit plus interface cards, so tell us your lines (fibre or copper internet, E1, serial, POS), how many users and sites, the VPN design and whether you need 3G/LTE backup. We will put together the whole configuration free of charge: model and version (1800-2S, (W) or (G)), interface cards per slot, SFP optics for the Combo ports, AC, DC or HVDC power and the second supply on the 2800-4/3800-8, and the service-engine level. For 3G/LTE we can first check which bands your local SIM actually uses at the site.
Access Router FAQ — ZTE Wantong ISG 1800 / 2800 / 3800
Which ISG model should I choose for my site?
Start from the number of users the manufacturer lists: 300–500 for the 1800-2S, 500–800 for the 2800-4 and 800–1,500 for the 3800-8. Then check interfaces: if you need E1 only, serial or 3G/LTE, the 1800-2S with its 2 SPIU slots is enough; if you need POS/CPOS, 10GE or more cards, or redundant power, go to the 2800-4 (5 slots) or 3800-8 (10 slots).
Can the router fall back to 4G/LTE when the fibre line goes down?
Yes. The 1800-2S(G) has 3G/LTE built in, and all three models accept a 3G/LTE interface card; listed modes are TD-SCDMA, WCDMA/HSPA+, TDD LTE and FDD LTE. Smart dial control (SDC) and link redundancy backup switch traffic to the cellular link when the wired line fails. The bands a module supports are not listed in the document, so we confirm them against your local operator before ordering.
Which VPN types can connect my branches to head office?
Over the public internet: IPSec VPN with IKE, DMVPN for many branches with dynamic addresses, GETVPN for group encryption, and GRE or L2TP tunnels. Over carrier networks: MPLS L2/L3 VPN and 6VPE, and MPLS VPN over GRE. VXLAN over IPSec or GRE is also listed for overlay designs. SM1–SM4 cryptography is supported where Chinese algorithms are required.
What is the difference in power and redundancy between the 1800-2S and the larger models?
The 1800-2S has a single supply, AC 100–240 V or DC -48 V, rated 60 W. The 2800-4 and 3800-8 take two supplies in 1+1 redundancy, with AC 100–240 V, HVDC 240 V/336 V (192–400 V) or DC -48 V, mixed AC and DC allowed, rated 250 W, and power supplies, fans and boards are hot-swappable. For sites that cannot go offline, VRRP between two routers and BFD are also supported.
Is the series ready for IPv6 and SDN WAN?
Yes, as listed: dual stack with RIPng, OSPFv3, IS-ISv6 and BGP4+, DHCPv6, MLD, and transition methods 6in4, 6to4, 4in6, 6 over 4, 6PE, NAT64, 6rd and ISATAP. For SDN WAN the document lists VXLAN, EVPN and NETCONF, including VXLAN over IPSec and over GRE. A specific SD-WAN controller is not named, so confirm with us which management platform your design relies on.
Can I order under my own company name and use my own forwarder?
Yes to both. Corporate buyers can have the purchase order submitted to the manufacturer under their own company name, so your company appears on the official order. For small and mid-size orders we also deliver directly to your designated forwarder's warehouse in China on EXW or FOB terms.
How do I view my CCTV remotely through an ISG router?
Two ways are supported by the listed features. Static NAT or PAT can publish the NVR's ports on the public address, protected by ACLs and the stateful firewall. The safer way is an IPSec VPN (or DMVPN for many sites) from each camera site to the monitoring centre, so the NVR is never exposed to the internet; H-QoS can reserve bandwidth for the video streams.
Why is there no throughput figure, and how do I size the router?
The manufacturer's document rates the series by recommended users — 300–500, 500–800 and 800–1,500 — and does not publish forwarding, NAT or IPSec throughput. Size by users first, then by lines and cards. If your design depends on a throughput figure (for example a 1 Gbps IPSec link), send us the requirement and we confirm it with the factory before quoting.
Does it work with Huawei, H3C or Cisco routers at the other end?
Through standard protocols, yes: OSPF, IS-IS and BGP, IPSec with IKE, GRE and L2TP tunnels, MPLS L2/L3 VPN, VRRP, BFD, PPP/PPPoE/HDLC, RADIUS/TACACS+, SNMP and NetFlow. DMVPN and GETVPN interoperability with other brands should be tested for your exact design, and the CLI is its own command set, so templates need translating.
Can I configure and manage it without the command line?
Yes for day-to-day work: a Web GUI is listed for service setup and maintenance, and new sites can be brought up from a USB drive or by SMS. Central teams can upgrade versions in batch from the NMS and monitor with SNMP v1/v2/v3, Syslog, NetFlow and SQA. Telnet and SSH remain available for advanced configuration.
Can these routers terminate E1 or older serial leased lines?
Yes, with interface cards: E1/CE1 and V.35/V.24 serial cards are listed for all three models, running PPP, HDLC or Frame Relay. The 2800-4 and 3800-8 also take OC-3/STM-1 POS/CPOS and OC-12/STM-4 POS cards for SDH lines. Each card uses a slot, so count your lines against 2, 5 or 10 slots.
Can I order one unit first, and how does it reach my country?
Yes — a single sample can be ordered and sent by air. For larger orders we deliver EXW or FOB to your freight forwarder's warehouse in China, or arrange air or sea freight to your country on request. Every shipment comes with a commercial invoice and packing list for customs; import duties and VAT in your country are not included unless agreed in writing.
How do I pay?
By bank transfer (T/T) in US dollars against our proforma invoice, which lists the model, quantity, unit price, delivery terms and lead time. You can check our company details on the verification page before you pay.
